Question

In a rectangle the length is 3metres more than its breadth and its perimeter is 22cm. Find the area of rectangle​

Answer 1

Answer:

Area = 28 cm²

Step-by-step explanation:

Let the length and breadth be l and b respectively.

Given,

l = b + 3

and, Perimeter = 2(l + b)

22 = 2(b + 3 + b)

11 = 2b + 3

2b = 8

b = 4 cm

l = 4 + 3 = 7

Area of rectangle = l × b = 7 × 4 = 28 cm²
