**Question: 545**

**2.** A rectangle with length 16 and width 6 has an area that is 3 times the area of a triangle with height 8. What is the length of the base of the triangle?

A. 4

B. 8

C. 12

D. 16

E. 22

**Correct Answer:** B

**Explanation:**

**B** If a rectangle has length 16 and width 6, then its area will be the length times the width, or 16 × 6, which equals 96. If this is 3 times the area of a triangle, then the triangle will have an area of 32. If a triangle with area 32 has height of 8, you can use the triangle formula for area of a triangle to find the base: × base × height = area. 32 = *b* × 8, so base × 4 = 32. This means that the base is equal to 8.
