Shaya plans to paint a bedroom wall that is shaped like a trapezoid. The bottom edge of the wall is 15.5 feet long, and the top edge of the wall is 15 feet long. If the wall is 8.5 feet tall, what is the area of the wall?

Answer 1

Mason Adams

Area of the trapezoid wall #color(magenta)(A_T = 988.125# #color(magenta)(ft^2#

Area of trapezoid #A_T = (1/2) (a + b) * h# where a & b are two parallel sides and h the height.

Given : #a = 15.5’, b = 15’, h = 8.5’#

#A_T = (1/2) * 15.5 * 15 * 8.5 = 988.125 # #ft^2#

To find the area of the trapezoid-shaped wall, you can use the formula for the area of a trapezoid, which is:

Area = (1/2) * (sum of the lengths of the parallel sides) * (height)

In this case, the lengths of the parallel sides are the bottom edge and the top edge of the wall. So, the area of the wall would be:

Area = (1/2) * (15.5 + 15) * 8.5

Area = (1/2) * 30.5 * 8.5

Area = 129.625 square feet.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
