I got -6b+16 is that right?
Answer:
1) 147
2) 87
Step-by-step explanation:
1) Area of triangle = × base length × height
=
× 14 × 10
= 70 
Area of a semicircle =
( r is the radius)
Radius = half of diameter =
= 7m
Area of semicircle = 
= 77
( Nearest whole number )
Total area = 77 + 70 = 147
2) Divide the shape into 2 rectangles
Area of a rectangle = length × width
Rectangle 1 = 7 × ( 3+3+5 )
= 7 × 11 = 77
Rectangle 2 = 2 × 5
= 10
Total Area = 77 + 10 = 87
