Question

perimeter of rectangle is equal to the perimeter of square .if the length and breath of the rectangle is 20 m and 10 m. find the area of square​

Answer 1

Answer:

A/Q

Perimeter of rectangle = perimeter of square

=》2(20+10)m =( 4×side)perimeter of square

=》 60m =(4×side) perimeter of square

=》Side of the square = 60/4

= 15m

Now,

Area of square = side × side

= 15m × 15m

= 225 m square

Answer 2

Answer:

Step-by-step explanation:

Perimeter of rectangle = 2 * l * b

                                      = 2 * 20 * 10

                                      = 60 m

Perimeter of square     =  Perimeter of rectangle

Perimeter of square     =  60 m

4a                                  = Perimeter of square

4a                                  = 60m

a                                    = 60/4 = 12m

area of square             =  a * a  = 12 * 12

                                    =  144 sq.m
