➷ As it is a trapezoid, we use this equation:
((a + b)/2) x h
a is the top length
b is the bottom length
h is the vertical height
Substitute in the given values:
((22.5 + 25)/2) x 19 4/5
Solve:
Area = 470.25ft^2 <== this is the answer

Answer:
43.17 ft/s
Step-by-step explanation:
Let the height of the wall is y.
distance of wall from light is 20 feet.
y = 20 tanθ .... (1)
time period, T = 3 second
Differentiate equation (1) with respect to t.
dy/dt = 20 x 2.16
dy/dt = 43.17 ft/s
Answer:
1/a^2 is the answer to this question
Perimeter=sum of all 3 sides
C. 1.5%, 0.125, 3/20, 1 4/5 is the correct answer
