The area of a trapezoid is one half of the product of its height and the sum of its bases.
4 mm
Practice makes perfect
From the picture we know some of the dimensions of the trapezoid. We want to find its height. Let's see the diagram!
Let's rotate the figures to help us recognize the dimensions.
The trapezoid has base lengths of 3 and 7 35 millimeters with an area of 21 15 square millimeters. The area of a trapezoid is one half the product of its height and the sum of its bases.
A=1/2h(b_1+b_2)
We can substitute the known values into this formula and solve for the height h. Let's do it!
