$\huge\mathcal\pink{Question:−}$

Power is in the shape of a rectangle rectangle its length is 40 cm and breadth is breath is 22 CM if the same wire is bent in the shape of a square what will be the measure of each side also find with which step and close more area??

$\huge\mathcal\pink{Answer:-}$

Length of wire in shape of rectangle =40 cm

Breadth of wire shape of rectangle =22 cm

let side of square made by wire be a

then ,

perimeter of rectangle = perimeter of square.

2(40+22)=4a

124=4a

a=31cm

Area of rectangle =40×22

=880cm ^2

Area of square =31×31

=961cm ^2

Square enclose more area then rectangle .
