What is the perimeter of the trapezoid in the figure?
To find the perimeter of the trapezoid, we will sum the lengths of all its sides. The given side lengths are:
Using the formula for the perimeter of the trapezoid, we have:
Substituting in the given values:
Performing the addition:
Therefore, the perimeter of the trapezoid is .
16
Given the trapezoid:
What is the area?
No! For perimeter, you simply add all four side lengths regardless of which ones are parallel. The trapezoid's special properties don't affect the perimeter calculation.
A trapezoid has four sides that can all be different lengths! The diagram shows: top base = 7.5, right leg = 4, bottom base = 1.5, and left leg = 3.
No! Treat all numbers the same way. Just line up decimal points when adding: 7.5 + 1.5 + 3 + 4 = 16.
Count your terms! You should have exactly 4 numbers being added together. If you have fewer than 4, you missed a side.
It doesn't matter for perimeter! Whether a side is 7.5 or 4 units long, you still add them all together. The position doesn't change the calculation.
