Question 68
5 times of the perimeter of a square is 600 cm. What will be the area of this square?
Solution
5 times of the perimeter of a square is 600 cm.
5 $$\times$$ perimeter of a square = 600
perimeter of a square = $$\frac{600}{5}$$ = 120 cm
$$4\times\ length\ of\ each\ side = 120$$
length of each side = 30 cm
Area of this square = $$\left(length\ of\ each\ side\right)^2$$
= $$\left(30\right)^2$$
= 900 $$cm^2$$
