Question

The base of a triangle is multiplied by 1/3. which of the following describes the effect of this change on the area? Help, Please!

Answer 1

The area is multiplied by 1/3

Explanation:

We have that the area of a rectangle is defined as follows:

`A=b\cdot h`

Now, we know that the base is 1/3 of the original base, so the new area would be affected like this:

`\begin{gathered} A^(\prime)=(1)/(3)b\cdot h \\ A^(\prime)=(1)/(3)(b\cdot h) \\ A^(\prime)=(1)/(3)\cdot A \end{gathered}`

Therefore, the area is multiplied by 1/3
