Question

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

Answer 1

(i) Given, length = 98m
Breadth = 18m
Area of rectangle = length $\times$ breadth
$=98\times 18$
$=1764m^2$

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