Question

The expression (1)/(2)a(b+c) can be used to find the area of the traperoid. What is the area of the trapezoid when a=5.5,b=5, and c=7.2?

Answer 1

The area of the trapezoid when a=5.5, b=5, and c=7.2 is calculated using the formula (1/2)a(b+c) to be 33.55 square units.

Step-by-step explanation:

The expression (1)/(2)a(b+c) is used to calculate the area of a trapezoid. To find the area when a=5.5, b=5, and c=7.2, we substitute these values into the expression:

Area = (1/2) × 5.5 × (5 + 7.2)

First, calculate the sum inside the parentheses:

b + c = 5 + 7.2 = 12.2

Now, plug this result back into the equation:

Area = (1/2) × 5.5 × 12.2

Next, perform the multiplication:

Area = 0.5 × 5.5 × 12.2

Area = 33.55 square units
