Answer:
7
Step-by-step explanation:
1/2 (37 + 4a) 8 = 260 260/8 = 32.5 32.5 * 2 = 65 65-37=28 28/4 = 7 a = 7
z=7
area = ½ × (a + b) × h.
260 = 37 + 4z × 8 ×0.5
260/0.5 = 520
520/8=65
37 + 4z = 65
65-37 = 28
28/4=7
last option is correct answer
22
5.50/0.25 = 22

The answer is D
(12 + 6) x ( 11 - 7) = 72
18 x 4 = 72
