Look at the trapezoid in the figure.
The long base is 1.5 times longer than the short base.
Find the perimeter of the trapezoid.
First, we calculate the long base from the existing data:
Multiply the short base by 1.5:
Now we will add up all the sides to find the perimeter:
17.5
Given the trapezoid:
What is the area?
Look at the diagram carefully! The short base is labeled as 5 units, and we're told the long base is 1.5 times longer. So the long base = units.
Because a trapezoid has four sides, not three! You're missing the long base. The perimeter needs all four sides: both legs (2 and 3), the short base (5), and the long base (7.5).
It means the long base is 1.5 times the length of the short base. So if the short base is 5 units, then: units for the long base.
Simple! Perimeter = sum of all sides for any polygon. For a trapezoid: P = leg₁ + leg₂ + short base + long base. Just add up everything around the outside!
Absolutely! Ratios can be decimals, fractions, or whole numbers. 1.5 means the long base is one and a half times the short base length.
