Answer:
The missing base measure of the enlarged trapezoid is 4cm.
Explanation:
Step 1:
2 / 3.25 = x / 6.5
Step 2:
Cross product
2 * 6.5 = 3.25 * x
Step 3:
Simplify
13 = 3.25x
Step 4:
Divide both sides by 3.25
13 / 3.25 = 3.25x / 3.25
4 = x
x = 4
The missing base measure of the enlarged trapezoid is 4cm.
