Question

The area of the triangle below is 5.88 square centimeters. What is the length of thebase?

Answer 1

The area of a triangle (At) is:

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

Where:

b is the base

h is the height.

Given that:

At = 5.88 cm².

h = 2.1 cm.

Substituting the values in the equation:

`5.88=(b\cdot2.1)/(2)`

To isolate b, multiply both sides by 2:

`\begin{gathered} 5.88\cdot2=(b\cdot2.1\cdot2)/(2) \\ 11.76=2.1b \\ (11.76)/(2.1)=b \\ 5.6=b \end{gathered}`

Answer: The length of the base is 5.6 cm.
