Question

the area of the triangle is 360 square millimeters. what is the triangles base, b? b = millimeters

Explanation:

Step1: Recall area formula

The area formula for a triangle is $A=\frac{1}{2}bh$, where $A$ is the area, $b$ is the base and $h$ is the height.

Step2: Rearrange the formula for $b$

We can rewrite the formula as $b = \frac{2A}{h}$.

Step3: Substitute given values

Given $A = 360$ square - millimeters and $h=40$ mm. Substitute into the formula: $b=\frac{2\times360}{40}$.

Step4: Calculate the value of $b$

First, calculate $2\times360 = 720$. Then, $\frac{720}{40}=18$ mm.

Answer:

18
