Can you solve this?
marusya05 [52]

Answer:

D

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = 0.5h(a + b)

where h is the perpendicular height and a, b the parallel sides.

Given A = 120, then

0.5 × 8(a + b) = 120, that is

4(a + b) = 120 ( divide both sides by 4 )

a + b = 30 cm → D

There is a </span><span>1,563 feet difference between the height of the bird and the depth of the fish</span>
