Find the area. 7 in. 5 in. 12 in.

vitfil [10]

Answer and Step-by-step explanation:

The area formula for a trapezoid is as follows:

A = $\frac{a + b}{2}h$

Where:

A = Area

a = top side length

b = bottom side length

h = height

Plug in the values given to you into the equation and solve.

A = $\frac{7 +12}{2}(5)$

A = $\frac{19}{2}(5)$

A = $\frac{95}{2}$

A = 47.5 $in.^2$ is the answer.

To show how you decided, the simple way would be to draw a picture. Create 2 rectangles of the same length and divide them up according to the fraction. Then shade the number of pieces for the numerator and compare both fractions. Whichever is longer is the greater fraction.

Step-by-step explanation:

Whole numbers is the only set of numbers in the following choices that don't include negative numbers (only positive integers and zero). Therefore, since -7 is negative, it doesn't belong to whole numbers!
