Look at the trapezoid in the diagram.
What is its perimeter?
In order to calculate the perimeter of the trapezoid we must add together the measurements of all of its sides:
7+10+7+12 =
36
And that's the solution!
36
Given the trapezoid:
What is the area?
Perimeter means the distance around the entire shape! Just like walking around the outside of the trapezoid, you must travel along every single side to complete the journey.
No problem! Just add whatever lengths are given. In this case: 7 + 10 + 7 + 12 = 36. The method stays the same regardless of the actual measurements.
Look for sides that never meet even if extended! In this trapezoid, the top side (10) and bottom side (12) are parallel because they go in the same direction.
Not at all! Perimeter only needs the side lengths, while area needs height and base measurements. These are completely separate calculations.
Make sure to examine the diagram carefully. Each side should have a number label. In this problem, you can see 10, 12, 7, and 7 marked on the four sides.
