Question

The perimeter of a rectangular sheet is 100 m. If the length is 35 m, find its area.

Answer 1

Answer:

area = 525 sq.m

Step-by-step explanation:

let the breadth of rectangle be x

perimeter = 2(l + b)

100 = 2(35 + x)

100 = 70 + 2x

100-70 = 2x

30 = 2x

30/2 = x

15 = x

so breadth of rectangle is 15m

area = l × b

= 35 × 15

= 525

so area of rectangle is 525 sq.m
