height: 1 yd area: 2.5 yd

Sagot :

We are told that we have a triangle of height h = 1 yd and an area of 2.5 squared yds and asked to find its base's length.

To do so, recall that the formula of the area of a triangle of height h and base b is

[tex]A=\frac{b\cdot h}{2}[/tex]

in our case, we have A = 2.5 and h = 1 . Then we have

[tex]2.5=\frac{b\cdot1}{2}[/tex]

If we multiply both sides by 2, we get

[tex]b=2.5\cdot2=5[/tex]

so the height of the triangle is 5 yd
