Question

find the perimeter of square whose area is equal to a rectangle of sides 14.40 metre and 10 metre​

Answer 1

let the side of square =x m

area of square=x ^2

now,area of square=area of rectangle

side^2 = length × breadth

x^2 = 14.40*10

x^2=144

x=12m

perimeter of square=4*side

=4*12=48m.
