If you draw a square of the same
perimeter, what will its area be?​

Answer 1

Answer:

pls mark as brainliest as it encourages me to help other's more :)

Step-by-step explanation:

Given: length of rectangle= 12 cm

breadth of rectange = 6 cm

Perimeter of this rectangle= 2(l+b) = 2 ( 12 +6 ) = 2 (18) = 36 cm

# Perimeter of rectangle =  perimeter of square

so, perimeter of square = 36 cm

which is, 4 * side = 36

side = 9 cm

Now, area of square = side * side

which is 9 *9 = 81 cm^2

Answer 2

Answer:

area of square = 81 cm^2

Step-by-step explanation:

l = 12 cm and b = 6 cm

perimeter of a rectangle = 2(l+b)

perimeter= 2(12+6)

               = 2(18) = 36 cm

let the side of the square be a

perimeter of square = 4a

4a = 36

a = 36/4 = 9

length of a square = 9 cm

area of a square  = a^2 (a*a)

area of square = 9^2(9*9)

                          = 81 cm^2
