Class 7 Maths Perimeter and Area Area of Parallelogram

Area of Parallelogram

A parallelogram is a 4-sided shape formed by two pairs of parallel lines. Opposite sides are equal in length and opposite angles are equal in measure as shown in the figure.

To find the area of a parallelogram, we multiply the base by the height.

Area of parallelogram = Base * Height

Problem: Find the area of each of the following parallelograms:

Solution:

We know that the area of parallelogram = base * height

(a) Here base = 7 cm and height = 4 cm

So, area of parallelogram = 7 * 4 = 28 cm2

(b) Here base = 5 cm and height = 3 cm

So, area of parallelogram = 5 * 3 = 15 cm2

(c) Here base = 2.5 cm and height = 3.5 cm

So, area of parallelogram = 2.5 * 3.5 = 8.75 cm2

(d) Here base = 5 cm and height = 4.8 cm

So, area of parallelogram = 5 * 4.8 = 24 cm2

(e) Here base = 2 cm and height = 4.4 cm

So, area of parallelogram = 2 * 4.4 = 8.8 cm2
