Find the area of a trapezoid that has one base length measuring 18 mm, one base measuring 16 mm, and a height of 9 mm. ___ mm²
To find the area of a trapezoid, you can use the formula:
Area = h(b1 + b2) / 2
where h is the height of the trapezoid, b1 and b2 are the lengths of the parallel bases.
In this case, the height (h) is 9 mm, the first base (b1) is 18 mm, and the second base (b2) is 16 mm.
Plugging the values into the formula, we get:
Area = 9(18 + 16) / 2
Area = 9(34) / 2
Area = 306 / 2
Area = 153 mm²
Therefore, the area of the trapezoid is 153 mm².
