Question

A rectangle piece of land having length 18 m has an area 440 ${m}^{2}$. Can it be used to make a square swimming pool having length 21 m?​

Answer 1

Given :-

Length of a rectangular piece of land = 18 m

The area of this rectangular piece of land = 440m²

Then , the measure of it's breadth will be :-

$= l \times b = 440 {m}^{2}$

$18 \times b = 440$

$b = \frac{440}{18}$

$\color{hotpink}b = 24.4$

The breadth of this rectangle is 24.4 m .

Length of one side of a square = 21 m

The area of this square :-

$= side \times side$

$= 21 \times 21$

$\color{hotpink} =441 {m}^{2}$

As the area of the rectangular piece of land is smaller than the area of the squarical swimming pool , it cannot be used to make the square shaped swimming pool .

∴ No , this rectangular piece of land can't be used to make the square swimming pool as it's area is smaller than that of the swimming pool's .
