Question

1:The area of a square is 625 cm. Find the side and perimeter of the square.
2:The area of a rectangular grassy field is 756 cm. If its length is 36 cm, find its breadth.
Also find its perimeter.​

Answer 1

Answer:

1. Area of square= a^2

a^2= 625

√a= 25

Therefore side= 25 cm

Perimeter=4a

4*25

= 100 cm

Therefore perimeter= 100 cm

2. Area= l*b=756 cm^2

l= 36

756=36*b

b= 756/36

b= 21

Therefore breadth= 21 cm

Perimeter=2(l+b)

=2(36+21)

=2(57)

= 114

Therefore perimeter= 114 cm.

Answer 2

Answer:

the side of square is 25 cm and perimeter is 100cm and the breadth of the Reactangle is 21 cm and perimeter is 114cm

Step-by-step explanation:

find the square root of the area that is 25

then multiply it with 4 that is 100 the perimeter

divide 756/36 that is 21 and then add 36+21 that is 57 and then multiply it with 2 that is 57×2 that is 114 cm
