Question

Write an expression to represent the perimeter of the rectangle:.

Answer 1

Answer:

a. 2x + 30

Step-by-step explanation:

The perimeter of a rectangle is represented by

2l + 2w

So substitute the rectangle values into the equation.

2(2/3(x) + 10) + 2(1/3(x) + 5)

Rewrite fractions for clarity.

2(2x/3 + 10) + 2(x/3 + 5)

Distribute the two into the first expression.

4x/3 + 20 + 2(x/3 + 5)

Distribute the two into the second expression.

4x/3 + 20 + 2x/3 + 10

Combine like terms.

6x/3 + 30

Simplify 6x/3.

2x + 30.
