Use this diagram to find the measures of the lengths of the sides. The perimeter of the trapezoid on the right is 97 inches.

irina [24]

Answer: 48 inches, 14 inches, 21 inches and 14 inches.

Step-by-step explanation:

1. The perimeter of the trapezoid is the sum of the lengths of its sides. You know that the perimeter is 97 inches, then, you can write the following expression:

$3.5x-1+x+x+1.5x=97\\7x-1=97$

2. Now, you must solve for x, as following:

$7x=97+1\\7x=98\\x=\frac{98}{7}\\x=14$

3. Then length of each side is:

$(3.5x-1)in=(3.5(14)-1)in=48in$

$1.5xin=(1.5)(14)in=21in$

$x=14in$
