Answer:
A. 120 ft
B. 119
C. 2100 ft
Explanation:
A. (Slipt the shape into 2 parts so it will be simpler)
For the triangle : 1/2 (4x12)
And for the rectangle : 12x8
1/2 (4x12) = 24
12 x 8 = 96
24 + 96 = 120 ft
_________________________________
B. (this time we can split it into 3 parts)
Longer rectangle : 12x6
Short rectangle : 5x5
Triangle : 1/2 (4x11)
LR : 12x6 = 72
SR : 25
T : 1/2 44 = 22
72+25+22 = 119

C. (Like the first one, we can split it into 2 parts)
Rectangle : 50x30
Triangle : 1/2 40x30
R : 1500
T : 1/2 1200 = 600
1500 + 600 = 2100
Hope this helps :)
