Question

Calculate the length of a rectangle if its perimeter is 250 m and breadth 45 m.

• A. 80 m
• B. 70 m
• C. 60 m
• D. 90 m

Answer 1

The correct option is A

80 m

Given, b = 45 m, and P = 250 m

Perimeter of a rectangle = 2 (l + b)

To calculate the length we use, P = 2 (l + b)

Therefore, 250 = 2 (l + 45)

i.e. $\frac{250}{2}$ = l + 45

$\Rightarrow$ 125 = l + 45
$\Rightarrow$ l = 125 - 45 = 80
