in this example we're asked to find the

area of the trapezoid shown remember

that a trapezoid is a quadrilateral with

one pair of parallel sides the formula

for the area of a trapezoid is area

equals one-half times parentheses base

one plus base two times height

where the bases are the parallel sides

so when the trapezoid shown the bases

are 15 inches and 25 inches and the

height is 5 inches plugging this

information into the formula we have 1/2

times 15 inches plus 25 inches times 5

inches next the order of operations

tells us that we must simplify inside

the parentheses first 15 inches plus 25

inches is 40 inches and we have 1/2

times 40 inches times 5 inches 1/2 times

40 inches is 20 inches and we have 20

inches times 5 inches which is 100

inches squared so the area of the

trapezoid shown is 100 square inches
