Question

the peremeter of the rectangle and square are same lenght and breadth of the rectangle are 10 cm and 8cm respectivly what is the area of square​

Answer 1

Answer:

81 cm^2

Step-by-step explanation:

Given: Length and breadth of the rectangle are 10 cm and 8 cm, perimeter of the rectangle and square are same.

To find:  area of the square=?

Solution:

So, we have given that perimeter of rectangle and square are same and length and breadth of the rectangle is also given, so first we need to find the perimeter of the rectangle.

Perimeter of rectangle is = 2(l+b)

                = 2(10 + 8)

                = 2(18)

                = 36 cm.

Now, perimeter of square is 4(a), where a is the side of square.

We have given that perimeter is equal so equate 4(a) with the perimeter of the rectangle, we get:

                4(a) = 36

                a = 9 cm

So the side of square is 9 cm.

Now area of square is 9 x 9 = 81 cm².

Answer:

                  So the area of the square is 81 cm².

Answer 2

Answer:

81

Step-by-step explanation:

Perimeter of the rectangle

= 2*length + 2* breadth

=2*10+2*8

=20+16

=36

Given:

perimeter of square = perimeter of rectangle= 36

Perimeter of square=4*side=36

side=36/4=9

Area of square= side*side=9*9=81

Area=81
