Question

Design An art class is making a mural for their school which has a triangle drawn in the middle. The

length of the bottom of the triangle is x. Another side is 13 more than two times the length of the
bottom of the triangle. The last side is 10 more than the bottom of the triangle. Write and simplify an
expression for the perimeter of the triangle.
What is the expression for the perimeter of the triangle?

Answer 1

Answer:
`4x+23`

Explanation:

Given

The length of the bottom of the triangle is x

Another side is
`2x+13`

The last side is
`x+10`

Perimeter is the sum of the side of triangles

`\Rightarrow \text{Perimeter}=x+2x+13+x+10\\\Rightarrow \text{Perimeter}=4x+23`
