Question

the length and breadth of a rectangular field are 90 M and 40 m if the area of rectangle is equal area of a square field find the perimeter of a square field

Answer 1

l×b=90×40
3600m square
area of rectangle = area of square
3600=s×s
3600 =side square
Side = 60cm
perimeter of square field =4 ×side
=4× 60
= 240 cm

Answer 2

Given: Area of Rectangle = Area of Square
To find: Perimeter of Square

Soln.: Area of Rectangle = length x breadth
                                        = (90 x 40) m²
                                        = 3600 m²

        ⇒ Area of Rectangle = Area of Square = (side)²
        ⇒ 3600 = (side)²
        ⇒ side = √3600
        ⇒ side = 60 m

        ∴ Perimeter of square = 4 x side
                                            = (4 x 60) m
                                            = 240 m

        Perimeter of Square Field = 240 m
