Question

explain it in brief ​

Answer 1

Answer:

Step-by-step explanation:

1. Area of a rectangle= length x breadth

length=15

breadth=10

thus,15x10

=150 cm^2

2. Area=256cm^2  = side x side or side^2

Thus, side= square root of 256= 16cm

perimter= side x 4

= 16 x 4

=64 cm

3. Perimeter of the square=Perimeter of the rectangle

length of rectangle=13 cm

breadth of rectangle= 11cm

perimeter = 2(l+b)

=2 (13+11)

=48

perimeter of square= 48  = 4 x side

side = 48/4

=12

area of a square= s^2

=12^2

=144 cm^2
