Question

If the perimeter of rectangle and circle are same. The perimeter of the square is 132 cm. Then find
i) Side of square
ii) Radius of circle
iii) Area of circle

Answer 1

Answer:

i) 33 ii) mark me as brainliest

Answer 2

Given,

• Perimeter of the square is 132 cm
• => 4 × Side = 132
• => Side = 132/4
• => Side = 33 cm

We have,

• Side of square is 33 cm

Also,

Perimeter of rectangle = Circumference of circle

=> 2(l + b) = 2πr

• {2 gets cancelled}

=> l + b = πr

=> r = (l + b)/π

And,

• Area of circle = π × r²

$\to \tt\pi \times { \bigg(\frac{l + b}{\pi}\bigg) }^{2} \\ \\ \to \sf \frac{ {( l+ b)}^{2} }{\pi} \: \: \: \: \: sq. \: units$
