Question

Find the perimeter of a square having the same area as that of a rectangle of length 8cm and breadth 2cm​

Answer 1

Step-by-step explanation:

area of rectangle = area of square

area of rectangle= length × breadth

=8 × 2 = 16cm = 1600m

area of square= a²

16 = a²

4 = a

perimeter= 4a

= 16.

Answer 2

Answer:

area of rectangle= length ×breadth = 8×2=16

area of square = area of rectangle= 16

area of square= side ×side= 16

side of square = 4

perimeter of square = 4×side =4×4=16.
