A trapezoid was broken into a rectangle and a triangle. What is the length, b, of the base of the triangle? 2 cm 4 cm 6 cm 8 cm

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

Step-by-step 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

16

step-by-step explanation:

2 x 40 = 80

80/5

= 16
