Question

A rectangular garden has an area of 132 m2 and a perimeter of 46m.

A = 132 m?

1. Write the expression representing the length in terms of its width.
(P = 21 + 2w)

Answer 1

l = 23-b

Explanation:

Given that,

Area of a rectangular garden, A = 132 m²

The perimeter of a rectangle, P = 46 m

Let l and b are length and breadth respectively.

Area, A = lb

lb = 132 ...(1)

Permeter, P = 2(l+b)

2(l+b)=46

(l+b)=23

l=23-b ...(2)

Hence, equation (2) shows the expression representing the length in terms of its width.
