Question

find the area of the following figure which are the combinations of different shapes

Pls help...​

Answer 1

Answer:

(1) = 49π/2 + 56

(2) = 49π/4 + 140

Step-by-step explanation:

(1).

Radius of semicircle = 7

Area of semicircle = (πR^2)/2

= 49π/2

base of triangle = 14

hight of triangle = 8

area of triangle = 1/2(base*hight)

= 56

then rotal area = 49π/2 + 56

(2).

Radius of semicircle = 7/2

Area of semicircle = (πR^2)/2

= 49π/8

and we have two semicircles

then area of the two semicircles=2(49π/8)

= 49π/4

length of rectangle = 20

width of rectangle = 7

area of rectangle = length * width = 140

then total area = 49π/4 + 140
