Answer:
12. The length of the other base of the trapeziod is 5 feet.
13. A, B, & C
Step-by-step explanation:
12. Area: 36
Height: 8
Base 1: 4
B= 2(36) -4
8
Step 1: Multiply 2 and 36; 72/8 - 4
Step 2: Divide 72 by 8; 9 - 4
Step 3: Subtract 9 and 4; B= 5
Solution: 5
13.
A. Area: 54 Height: 3 Base 1: 6 Base 2: 30
30 = 2(54) - 6
3
30 = 108/3 - 6
30 = 36 - 6
30 = 30
B. Area: 54 Height: 3 Base 1: 9 Base 2: 27
27 = 2(54) - 9
3
27 = 108/3 - 9
27 = 36 - 9
27 = 27 in
C. Area: 54 Height: 3 Base 1: 12 Base 2: 24
24 = 2(54) - 12
3
24 = 108/3 - 12
24 = 36 - 12
24 = 24 in
D. Area: 54 Height: 3 Base 1: 18 Base 2: 2
2 = 2(54) - 18
3
2 = 108/3 - 18
2 = 36 - 18
2 ≠ 18
E. Area: 54 Height: 3 Base 1: 36 Base 2: 1
1 = 2(54)/3 - 36
1 = 108/3 - 36
1 = 36 - 36
1 ≠ 0
