Question

A rectangle has a links of 5" and a with of X inches write a equation to represent the perimeter of the rectangle explain your reasoning

Answer 1

10+2x

Explanation:

A rectangle has 4 sides. Two pairs of sides are congruent.

For example a rectangle could have sides of 6, 10, 6, and 10.

So the perimeter would be the sum of those sides, 6+6+10+10.

6+6+10+10 can be written like 2(6)+2(10)

For the rectangle in your question it would be 5+5+x+x, which can be written like 2(5)+2(x)

Simplify to 10+2x.
