Question

the length and the breadth of a rectangular field are 90m and 40m if the area of a rectangular field is equal to the area of a square field, find the perimeter of the square field?

Answer 1

Area of rectangular field = length × breadth
area = 90×40 = 3600m^2
area of square = 3600 m^2
let the side of square fiels be a
area of square= a × a
3600= a^2
a= 60 m
perimeter of square= 4 × side
perimeter= 4×60= 240m
