Question

The perimeter of a square plot is the same as that of a rectangular plot with sides $35 \; \text{m}$ and $15 \; \text{m}.$ The side of the square plot is :

• A. $25 \; \text{m}$
• B. $20 \; \text{m}$
• C. $100 \; \text{m}$
• D. $50 \; \text{m}$

Answer 1

perimeter of square= $4a$

perimeter of rectangle=$2(l+b)$

it is given that :

$4a=2(l+b)$

$\implies 4a=2(35+15)m$

$\implies a=\frac{2*50}{4}=25 m$

Option (A) is correct.
