a triangle has an area of 230. 86 square inches. The height of the triangle is 23.8 inches. What is the length of the base of the triangle?



Sagot :

Given;
Area of the traingle = 230.86 sq. inches
Height of the triangle = 23.8 sq. inches

We have,
Area of the triangle =  [tex] \frac{1}{2} bh[/tex]
where,
b = base of the traingle
h = height of the triangle
Now,
Substituting the given info. we get,
[tex]230.86 = \frac{1}{2} ~ b~(23.8)[/tex]

[tex] \frac{230.86 ~*~2}{23.8} = b[/tex]

[tex]b = 19.4[/tex]

So, the base of the triangle is 19.4 inches
