Question

The difference between the length and breadth of a rectangle is 23 metre if its perimeter is 206 metre.Then its area is

Answer 1

Answer:

Step-by-step explanation:

Let breadth = x

Let length = x + 23

Perimeter = 206 mt

2(l+b) = 206

2 ( x + 23 + x ) = 206

2 ( 2x + 23 ) = 206

2x + 23 = 206/2

2x + 23 = 103

2x = 103 - 23

2x = 80

x = 80/2 = 40

L = x + 23 = 40 + 23 =63

B = x = 40

Area = l × b

= 63 × 40

= 2520m²
