Equilateral triangle mnp has perimeter 12a+18b. line segment qr is a midsegment. what is qr?

qr = 2a + 3b

Step-by-step explanation:

First, we must calculate the measure of each side based on the perimeter. Since all three sides of an equilateral triangle are equal, we divide the perimeter by 3.

4a + 6b (measure of each side)

Being an equilateral triangle, any middle segment is half the length of any of its sides.

So, the value of qr is:
