Question

The estimated area of a triangle is 12 in^2. The height of the triangle is 8.2 inches. What is the estimated base of the triangle.A.) 3 inches B.) 12 inches C.) 4 inches D.) 6 inches

Answer 1

The area of a triangle is given by:

`A=(b\cdot h)/(2)`

Where:

b = base

h = height = 8.2

A = Area = 12

Therefore:

`\begin{gathered} b=(2A)/(h) \\ b=(2(12))/(8.2) \\ b=2.9268in \\ b\approx3in \end{gathered}`

Answer:

A) 3 inches
