This composite figure consists of a right triangle and semicircle
The area of a triangle is: 1/2(bh)
The area of a semicircle is 1/2(pi)(r²)
Plug in the values:
1/2( 12)(8)
=48
1/2(3.14)(4²)
=25.12
25.12+48=73.12
Hope this helped :)
2x+6 = 20
take 6 from both sides
2x = 14
divide by 2 on both sides
x = 7
Your answer is 62.5. Hope i helped
