Answer 1

Answer:

Given Find the area of an invitation card which has two semicircles

attached to a rectangle as in the figure given.

22

30 cm

We know that  

Area of rectangle = length x breadth

                            = 22 x 30

                            = 660

We know that

Area of semi circle = area of circle /2

1. 3.14 x 11 x 11 / 2 = 379.94 / 2 = 189.97 (half of 22 = 11)

2. 3.14 x 15 x 15 / 2 = 706.5 / 2 = 353.25 (half of 30 = 15)

Now adding all the areas we get

189.97 + 353.25 + 660 = 1203.22 cm
