Question

Find the area of a square whose perimeter is $100cm$.

Answer 1

Step 1:

Perimeter of square$=4\times side$

Perimeter of square$=100cm$

Side of square$=\frac{Perimeter}{4}$

Side of square$=\frac{100}{4}=25cm$

Step 2:

Area of square$=side\times side$

Area of square$=25\times 25=625c{m}^2$

Hence, area of square whose perimeter is $100cm$ is $625c{m}^2$.
