Trapezoid Perimeter: Finding the Total Length with a 1.5 Base Ratio

Question

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.

00:00 Calculate the perimeter of the trapezoid

00:05 The perimeter of the trapezoid equals the sum of its sides

00:28 Substitute the side value according to the given ratio

00:43 Substitute appropriate values and solve to find the perimeter

01:09 And this is the solution to the question

First, we calculate the long base from the existing data:

Multiply the short base by 1.5:

$5\times1.5=7.5$

Now we will add up all the sides to find the perimeter:

$2+5+3+7.5=7+3+7.5=10+7.5=17.5$

17.5
