Question

Find the length of each side of a square whose area is equal to the area of a rectangle length 13.6 metres and breadth 3.4 metres.​

Answer 1

Answer:

it was 6.8 m

Step-by-step explanation:

area of rectangle= area of square

let the sides of a square = a

therefore, a square= l*b (where l is length of rectangle and b is breadth of rectangle)

solving it we get a=✓13.6 x 3.4

a= 6.8m

Answer 2

The area of rectangle = length × breadth

                                     = 13.6 × 3.4

                                     = 46.24 m²

let the sides of square be 'a'

then area of square = a²

but we are given that area of square is equal to area of rectangle

∴  a² = 46.24

     a =$\sqrt{46.24}$

        =6.8
