Question

find the area of following figure​

Answer 1

Answer:

109.25

Step by step explanation:-

Area = Area of semi circle + area of rectangle + area of ∆

= 1/2πr² + l×b + 1/2 (b × h)

= 1/2 × 22/7 × 3.5 × 3.5 +10 × 7 + 1/2 × 4 ×10

=11 × 3.5/2 + 70 + 20

= 11× 35/20 + 90

= 11 × 7/4 + 90

= 77/4 + 90

= 77 + 360

4

= 437

4

= 109.25

Answer 2

area of semi circle = pie*r*r/2=19.25cm^2

area of rectangle = l*b= 70cm^2

area of triangle = 1/2*b*h

=20cm^2.

add all areas and you will get 109.25
