A triangle has an area of 20 cm2 and a height of 5 cm. How long id the base?

RideAnS [48]

The base of given triangle is 8 cm.

Further explanation:

The area of triangle is calculated by using two methods

Hero's formula
Base and Height

Hero's formula requires all three sides of triangle while we can use only base and height in second formula.

Given

$A = 20\ cm^2\\h = 5\ cm$

As the area of triangle and height are given, then

$A = 0.5*b*h\\20=0.5*b*5\\20=2.5b\\b=\frac{20}{2.5}\\b=8\ cm$

The base of given triangle is 8 cm.
