1. To solve this exercise, you must apply the formula for calculate the area of a trapezoid, which is shown below:

A=(b1+b2/2)h

A is the area of the trapezoid.
 b1 is the larger base of the trapezoid (b1=16-4=12 ft).
 b2 is the smaller base of the trapezoid (b2=10-4=6 ft).
 h is the height of the trapezoid (h=12-4=8 ft)

2. When you substitute these values into the formula A=(b1+b2/2)h, you obtain:

A=(b1+b2/2)h
 A=(12 ft+6 ft/2)(8 ft)
 A=9 ftx8ft
 A=72 ft²

3. The length of fencing is: a²=b²+c² a=√b²+c² a=√(8 ft)²+(6 ft)² a=10 ft Perimeter (Length of fencing)=12 ft+8 ft+6 ft+10 ft=36 ft

Answer:

Option A. 64,500

Explanation:

1. First, calculate the number of hits had during the month, by difference:

50,165 hits - 7,278 hits = 42,887 hits

2. Round the result to obtain an approximation = 43,000 hits

3. Multiply by the time that each lasted:

43,000 hits × 1.5 min/hit = 64,500 minutes.

Hence, the answer is the option A.
