Question

Someone help please

Answer 1

Explanation:

Semicircle:

diameter = 6 yd

r = 6/2 = 3 yd

`Area \ of \ semicircle = (1)/(2)\pi r^(2)\\\\`

`=(1)/(2)*3.14*3*3\\\\= 14.13 \ yd^(2)`

Triangle:

base = b =6 yd

height = h = 4 yd

`Area \ of \ triangle = (1)/(2)bh\\\\`

`=(1)/(2)*6*4\\\\\\= 3*4\\\\= 12 \ yd^(2)`

Area of composite figure =area of semicircle + area of triangle

= 14.13 +12

= 26.13 yd²
