Question

A child prepares a poster on save energy on a square sheet whose each side measures

60cm.At each corner of the sheet, she draws a quadrant radius 17.5cm, in which she

shows the ways to save energy. At, the centre she draws a circle of diameter 21cm

and writes slogan “Save energy” in it. Find the area of the remaining sheet​

Answer 1

⭐Answer⭐

Area of the square = 60 * 60 = 3600 cm square

We will get required area by subtracting area of 4 quadrant and the central circle from the area of the square

Area of the remaining sheet = 3600 - π(21/2)2 - 4* π/4*(17.5)2

= 3600 - π(441/4 + 1225/4)

= 3600 - 22/7 * 1666/4

= 3600 - 1309

= 2291 cm square.
