For the following trapezoid, h = 5 ft, b = 7.9 ft, and B = 14.6 ft. What is the area?

Bond [772]

Answer:

The area of the trapezoid is 56.25² feet.

Step-by-step explanation:

The formula for the area of a trapezoid is $A=\frac{b+B}{2} h$

A = area (of the trapezoid)
b = base of the trapezoid
B = (other) base of the trapezoid
h = height of the trapezoid

*Note: Trapezoids have 2 bases that are parallel to one another, but are not always the same length.

Using the information given to us, we can simply plug in numbers into the equation. By doing so, we'd get $A=\frac{7.9+14.6}{2} 5$ . By plugging this into a calculator, you'd get $A=56.25$ .

How do I solve this problem?

Ivenika [448]

Use the Pythagorean Theorem.
a^2 + b^2 = c^2
2^2 + 3^2 = c^2
4 + 9 = 13
square root of 13 = 3.6055...
round to the nearest hundredth..
The answer is 3.61 cm
