A triangular sail has a base length of 2.5 meters. The area of the sail is 3.75 square meters. How tall is the sail?
WARRIOR [948]
Hi, Idgagirls! :)

We can figure out how tall the sail is with the formula to the find the area of a triangle, which is:
b*h/2
b=base
h=height


Lets insert the information we already know:
2.5h/2=3.75
Solve for h.
Divide both sides by 2.5.
(2.5h/2)/2.5=(3.75)/2.5
Simplify.
h/2=1.5
Multiply both sides by 2.
(h/2)*2=(1.5)*2
h=3

The sail is 3 meters high.

Hope this helps.

To find which fractions are equal to each other, we must simplify or multiply to both denominator and numerator:

          \frac{2}{6} =\frac{1*2}{3*2} =\frac{1}{3}*\frac{2}{2}=\frac{1}{3}*1=   \frac{1}{3} \\\\\frac{8}{1}=8\\ \\\frac{2}{4} =\frac{1*2}{2*2} =\frac{1}{2}*\frac{2}{2} =\frac{1}{2} *1= \frac{1}{2} =\frac{1}{2}*1 =\frac{1}{2}*\frac{4}{4} =\frac{1*4}{2*4}=\frac{4}{8}   \\\\\frac{2}{8} =\frac{1*2}{4*2}=\frac{1}{4}*\frac{2}{2} =\frac{1}{4} *1  =\frac{1}{4} \\\\\frac{4}{4} =1

Hope that helps!
