Question

9. The difference between the length and
breadth of the rectangle is 23 m. If its
perimeter is 206 m, then its area is
(a) 2120 m²
(b) 2480 m
(c) 2520 m
(d) 2720 m
​

Answer 1

Let length = x m

Let breadth = y m

x - y = 23 m ——> 1

Perimeter = 2(x + y)

2(x + y) = 206

x + y = 103 ——> 2

Adding 1 & 2, we get

2x = 126

x = 63

y = 40

Area of rectangle = x * y = 63*40 = 2520 sq mts

Answer is Option C
