Question

Andy spent ₹450 in fencing the parallelogram shaped land at the rate of ₹5 per metre. If the length of the land is 25m , then find the width of the land.

• A. Rs. 437.47
• B. Rs. 444
• C. Rs. 431.47
• D. Rs. 438

Answer 1

The correct option is D

Rs. 438

Amount spent on fencing = ₹ 450

Rate = ₹ 5 per metre

$\therefore$ Perimeter = $\frac{450}{5}=90m$

Length = 25 m. let breadth be = b m

2( l + b) = 90

$\Rightarrow$ 2(25 + b) = 90

$\Rightarrow$ 25 + b = 45

$\Rightarrow$ b = 20m
