The Are Of The Triangle Below Is 288 Square Centimeters What Is The Length Of The Base class=

Sagot :

Take into account that the formula for the area of a triangle is:

A = b·h/2

where b is the base, h is the height h = 7.2 cm and A is the area A = 28.8 cm²

Solve for b in the previous formula, and replace the values of A and h, as follow:

b = 2·A/h

b = 2(28.8 cm²)/(7.2 cm)

b = 8 cm

Hence, the length of the base of the triangle is 8 cm
