Question
The trapezoid shown has an area of 1,575 sq cm.
Which equation could you solve to find the height of the trapezoid?
Solution
To find the height of a trapezoid when you know its area, you can use the formula for the area of a trapezoid:
where:
- is the area,
- and are the lengths of the two parallel sides (bases), and
- is the height.
Given the area , you can rearrange the formula to solve for the height :
-
Start with the formula for the area of a trapezoid:
-
Substitute the known area into the equation:
-
To isolate , multiply both sides by 2:
-
Finally, divide both sides by :
Final Answer
The equation you could solve to find the height of the trapezoid is:
