The area of a triangle is 1,440 cm2. The base of the triangle is 5 times the height. What is the height of the triangle?

madam [21]

Answer: 24 cm

Step-by-step explanation:

The formula for calculate the area of a triangle is:

$A=bh/2$

Where b is the base and h is the height.

Then if the base of the triangle is 5 times the height:

$b=5h$

Substitute the above into the formula and solve for the height. Therefore, you obtain that the height is:

$1,440=\frac{5h*h}{2}\\1,440=\frac{5h^{2}}{2}$

$1,440cm^{2}=5h^{2}/2\\h=\sqrt{\frac{2(1,440)}{5}}\\h=24cm$
