Question

Find the area of the figure.​

Step by step

Answer 1

Solution:

Area of the rectangle= Length*breadth

= 12 cm* 7 cm

= 84 cm^2

Area of the semi circle= 1/2*pi*r^2

= 1/2* 22/7*7^2

= 1/2* 22/7* 49

= 77 cm^2

Area of the 2nd semi circle

= 1/2*pi*r^2

=1/2*22/7*47= 77 cm^2

The area of the figure= 77 cm^2+ 77 cm^2 + 84 cm^2

= 238 cm^2

Answer 2

Step-by-step explanation:

when you will add that two semi circle then it will became a circle and its diameter will be 7cm and radius 3.5cm . Formula of area of circle =πr2

So. 22/7×7×7=154

Then area of rectangle

l×b=12×7=84

Then area of full figure

area of circle +area of rectangle

=154+84

=238
