Question

Are the only bases that I need to use 2 and 4 along with the height 2.5 and I just ignore the 3?

Answer 1

Answer:

$7.5\ units^2$

Step-by-step explanation:

The formula to find the area of a trapezoid is the following,

$A=(h)(\frac{(b_1)+(b_2)}{2})$

Where ($h$) represents the heights of the trapezoid, ($b_1$) and ($b_2$) represent the bases of the trapezoid, or rather the two parallel sides of the trapezoid.

One is given all of these values in the picture,

$h = 2.5\\\\b_1 = 2\\\\b_2 = 4$

Substitute these values into the formula and solve for the area of the trapezoid,

$A=(2.5)(\frac{(2)+(4)}{2})$

Simplify,

$=(2.5)(\frac{6}{2})\\=(2.5)(3)\\=7.5$
