Question

A trapezoidal deck has an area of 96m^2. The front and back widths are 6m and 10m, as shown. What is the length of the deck from front to back.

Answer 1

Answer:

3m

Step-by-step explanation:

we know area of trapezoid is 2h(l+b)

here we need to find out h, so

96 = 2h(6+10)

h = 3m

Answer 2

Answer:

h = 12m

Step-by-step explanation:  

area of trapezoid = h(l+b)/2

so by this logic:

96 = h(6+10)/2

h = 12m
