Question

The perimeter of the triangle shown is 40 meters. Write an equation to represent the

perimeter and then solve for the value n.


The sides of the triangle are 11m, (2n+3)m and 16m

Answer 1

15m

Explanation:

perimeter=total distance round a figure

40m=11m+16m+2n+3m

40m=30m+2n

50m-30m=2n. 30=2n. (divide both sides by 2 to get). n=15m
