Question

Find the length of each side of a square whose area is equal to the area of the rectangle of length 98 m and breadth 18 m.

Answer 1

Given, length = 98m
Breadth = 18m
$\text{Area of rectangle}=length\times breadth$
$=98\times 18$
$=1764m^2$
$\text{Given, area of square = area of rectangle}=1764m^2$
$\text{Area of square}=(\text{side}{)}^2$
$1764=(side{)}^2$
$\text{Side}=\sqrt{1764}=42m$
Therefore the length of the side of the square = 42 m.
