The formula for the area of a triangle is A=(1/2)ab, where b is the base of the triangle and a is the altitude of the triangle.

(a) Use this formula to find the base of a triangle that has an area of 60 square meters and an altitude of 12 meters.

A = 60 m^2

a = 12 m

b = ?

(1/2)ab = A

(1/2)*12b = 60

by solving we find

b = 10 m

(b). Use this formula to find the altitude of a triangle that has an area of 88 square meters and a base of 11 meters.

A = 88 m^2

b = 11 m

a = ?

(1/2)ab = A

(1/2)a*11 = 88

by solving we find:

a = 16 m
