Question 1169859
<br>
Given that the base and the height are in the ratio of 5:3, start with<br>
5x = base
3x = height<br>
Then use the formula for the area of a triangle (one-half base times height) with the given area to solve for x.<br>
{{{(1/2)(5x)(3x) = 43.2}}}
{{{15x^2 = 86.4}}}
{{{x^2 = 86.4/15 = 5.76}}}
{{{x = 2.4}}}<br>
ANSWERS:
base = 5x = 12m
height = 3x = 7.2m<br>
