Step-by-step explanation:
(a)
The shaded figure is a trapezium with area (A)
A = 0.5 h(a + b)
where h is the perpendicular height and a, b the parallel sides, thus
A = 0.5 × 10 × (8 + 14) = 5 × 22 = 110 cm²
(b)
The volume (V) of the prism is calculated as
V = area of end face × depth
= 110 × 3 = 330 cm³

Step-by-step explanation:
Ratio is Joey/girlfriend = 8/7=8x/7x.
8x is height of Joey.
8x=72
x=72/8=9
7x is height of Joey's girlfriend.
7x=7*9=63 in.
Answer: 63 in.
