Answer:
63 yd²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A =
h (a + b)
where a and b are the parallel bases and h the perpendicular height.
Here a = 8, b = 10 and h = 7, thus
A = 0.5 × 7 × (8 + 10) = 0.5 × 7 × 18 = 63 yd²
Rosa can run 3 miles in 42 minutes. As you can see in the work above, by using a proportion and solving it you can find the answer.
