In class 6 Maths, we have studied the area and parameters of some regular shapes such as the rectangle and the square. Now, in NCERT Solutions Class 7 Maths Chapter 9, we will learn to determine the area and parameters of some parallelograms and triangles. Later in the chapter, we will also learn to determine the area and circumference of circles. Let us now have a look at the NCERT Solutions Class 7 Maths Chapter 9 Perimeter and Area (PDF).\u00a0\u00a0<\/p>\n\n\n\n

Top 10 Short Maths Tricks for Comple\ud835\udc65 Problems<\/strong><\/p>\n\n\n\n

Topic 1: Area of a Parallelogram<\/h3>\n\n\n\n

The area of a parallelogram can be calculated by multiplying the length of its base with height.\u00a0<\/p>\n\n\n\n

Area of a Parallelogram = Base \u00d7 Height<\/p>\n\n\n\n

Topic 2: Area of a Triangle<\/h3>\n\n\n\n

The base and the height of the triangle are the same as the base and the height of the parallelogram, respectively. But the area of a triangle is half the area of the parallelogram of the same height and base. Hence, the area of a triangle can be calculated by multiplying the lengths of its base and height with \u00bd.\u00a0<\/p>\n\n\n\n

Area of a Triangle = \u00bd \u00d7 the area of the parallelogram<\/p>\n\n\n\n

\u2234 Area of a Triangle = \u00bd \u00d7 (Base \u00d7 Height)<\/p>\n\n\n\n

Topic 3: Circumference of a Circle<\/h3>\n\n\n\n

The distance around a circular region is known as its circumference.<\/p>\n\n\n\n

Circumference of a circle = 2\ud835\udf0br<\/p>\n\n\n\n

Topic 4: Area of a Circle<\/h3>\n\n\n\n

The area of a circle can be calculated by the following formula.<\/p>\n\n\n\n

Area of a circle = \ud835\udf0br2<\/sup><\/p>\n\n\n\n

Q 1. Find the area of the following parallelogram.<\/strong><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Solutions.<\/strong> We know that the area of a parallelogram can be calculated by multiplying the length of its base with height.\u00a0<\/p>\n\n\n\n

In the given parallelogram, base = 7 cm and height = 4 cm.<\/p>\n\n\n\n

\u2234 area of the given parallelogram = base \u00d7 height = 7 cm \u00d7 4 cm = 28 cm2<\/sup><\/p>\n\n\n\n

Q 2. Find the area of the following triangle.<\/strong><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Solutions.<\/strong> We know that the area of a triangle can be calculated by multiplying the lengths of its base and height with \u00bd.\u00a0<\/p>\n\n\n\n

In the given figure, the height of the triangle is 3 cm long and its base is 4 cm long.\u00a0<\/p>\n\n\n\n

\u2234 Area of a Triangle = \u00bd \u00d7 (Base \u00d7 Height) = \u00bd \u00d7 3 cm \u00d7 4 cm = 6 cm2<\/sup>.<\/p>\n\n\n\n

Q 3. PQRS is a parallelogram. QM is the height from Q to SR and QN is the height from Q to PS. If SR = 12 cm and QM = 7.6 cm. Find:<\/strong><\/p>\n\n\n\n

    \n
  1. the area of the parallelogram PQRS<\/strong><\/li>\n\n\n\n
  2. QN, if PS = 8 cm<\/strong><\/li>\n<\/ol>\n\n\n\n
    \"\"<\/figure>\n\n\n\n

    Solutions. <\/strong>We can determine the area of a parallelogram by multiplying the length of its base with height.\u00a0<\/p>\n\n\n\n

      \n
    1. The base and height of the given parallelogram PQRS are 12 cm and 7.6 cm respectively.<\/li>\n<\/ol>\n\n\n\n

      \u2234 area of the given parallelogram = base \u00d7 height = 12 cm \u00d7 7.6 cm = 91.2 cm2<\/sup><\/p>\n\n\n\n

        \n
      1. The area of the parallelogram remains the same even if we consider the base and height to be PS and QN respectively.<\/li>\n<\/ol>\n\n\n\n

        \u2234 area of the given parallelogram = base \u00d7 height\u00a0<\/p>\n\n\n\n

        Given: PS (base) = 8 cm and QN (height) = ?<\/p>\n\n\n\n

        \u21d2 91.2 cm2<\/sup> = 8 cm \u00d7 QN<\/p>\n\n\n\n

        \u21d2 QN = 91.2 cm2<\/sup>\/8 cm = 11.4 cm<\/p>\n\n\n\n

        Thus, the length of the perpendicular QN is 11.4 cm.<\/p>\n\n\n\n

        Q 1. Find the circumference of the circle with a radius 14 cm.<\/strong><\/p>\n\n\n\n

        Solutions. <\/strong>We know that the circumference of a circle is 2\ud835\udf0br.\u00a0<\/p>\n\n\n\n

        So, Circumference of a circle = 2\ud835\udf0br = 2 \u00d7 22\/7 \u00d7 14 cm = 88 cm<\/p>\n\n\n\n
