Question

A square and a parallelogram have the same area. If the side of the square is 48 m and the height of the parallelogram is 18 m. Find the length of the base of the parallelogram

Sum

Solution

Given side of the square is 48 m

Area of the square = (side × side) sq.unit

= 48 × 48 m2

Height of the parallelogram = 18 m

Area of the parallelogram = ‘bh’ sq.units

= b × 18 m2

Also area of the parallelogram = Area of the square

b × 18 = 48 × 48

b = `(48 xx 48)/18`

= 8 × 16

= 128 m

Base of the parallelogram = 128 m
