Question

solve this plzzzz...A paper is in the form of a rectangle ABCD in which AB=20cm andBC=14cm.A semi-circular portion with BC as diameter is cut off.Find the area of the remaining part​

Answer 1

Answer:

Tan 20

you find the area of your own

Answer 2

area of rectangular paper = (length x breadth)

= 20 x 14

= 280 sq cm

area of semicircle = (πr^2)/2

r = 14/2 = 7 cm

area = 22/7 x 7^2 / 2

= 154 / 2

= 77 sq cm

area of remaining part = area of rectangle - area of circle

= 280 - 77

= 203 sq cm
