Question

find the area of a circle whose perimeter is twice the perimeter of a square with area of 25 m.​

Answer 1

Answer:

area of square = 25

as we know area of square is side × side

√25= 5×5

one side of square = 5 m

perimeter of square= 5×4=20m

perimeter of circle = 2×20m=40m

as we know 2πr= perimeter

2×22/7×r=40

r= 6.3

area = πr^2

22/7×6.3×6.3

=124.74

Answer 2

Answer:

as we know that area of square is 25m2

and area of square is (side)2 = (5)2

therefore the side of square is side=5m

then we need to find perimeter of square

= 4*side = 4*5 = 20m

now the perimter of circle is twice the perimeter of square =2*20m = 40m answer
