Question

Find the side of a square, whose area is equal to the area of a rectangle with sides 6.4m and 2.5m. Also find the perimeter of the square.

Answer 1

Answer:

side =4

Step-by-step explanation:

arae of rectangle=l×b=6.4×2.5=16m²

as area of square and rectangle is equal

area of square=side²

therefore 16m²=side²

√16=side

4= side.

Answer 2

Answer:

Area of a rectangle is=  l x b

Area of this rectangle is= 6.4m x 2.5m

                                       = 16m²

The side of the square is= $\sqrt{16}$

                                         = 4

∴ One side of a square with same area of a triangle= 4

Perimeter of a square= S x 4

∴Perimeter of the square= 4 x 4

                                      = 16m
