Answer:
A trapezoid was broken into a rectangle and a triangle. What is the length, b, of the base of the triangle?
The correct answer to the question is 4 cm
Explanation:
The trapezoid with sides 10 cm, 12 cm, and 14 cm to look for the length of the base of the triangle formed by braking the trapezoid into rectangle and a triangle
Please see attached diagram
The length of the trapezoid = 14 cm
The opposite parallel side = 10 cm
When the trapezoid is broken along the second end of the opposite parallel side to form a rectangle with length 10 cm by 12 cm as shown below, the base b of the triangle will then have a length of 4 cm so that
Length of base of triangle + length of base of rectangle = original length of base of trapezoid
The answer is 4 cm
