The area of a rectangular ground is 12500 \( \Large m^{2} \). If its length is 125 m, then its perimeter is

A) 250 m
B) 550 m
C) 450 m
D) 500 m

Correct Answer:



C) 450 m

Description for Correct answer:
Area of rectangle (A) = \( \Large l \times b \)

\( \Large 12500 = 125 \times b \)

Therefore, \( \Large b = \frac{12500}{125} \)

Therefore, b = 100 m

Now perimetre of rectangle = \( \Large 2 \left(l+b\right) \)

= \( \Large 2 \left(125+100\right) \)

= 450 m
