Question

Find the area of the shaded region in the fig., where ABCD is a square of side 28 cm.
​

Answer 1

Answer:

radius of circle = 7cm

area of 1circle= πr^2= 153.93cmsq

then area of 4circles= 153.93× 4= 615.75cmsq

area of square= a^2= 28^2= 784cmsq

therefore area of shaded region = 784- 615.75

= 168.25

Step-by-step explanation:

so the answer is 168.25cmsq

hope it help you

Answer 2

Answer:

Area of the shaded region is 42 cm².

Step-by-step explanation:

Area of square ABCD = Side²

• 14 × 14
• 196 cm²

Diameter of each circle = 14/2 = 7 cm

Radius of each circle = 7/2 = 3.5 cm

Area of 1 circle (πr²) = 22/7 × 35/10 × 35/10

• 154/2
• 71/2 cm²

Area of four circles = 4 × 71/2

• 154 cm²

Area of shaded region = 196 cm² - 154 cm²

• 42 cm²

∴ Area of the shaded region is 42 cm².
