The rectangle below has a total perimeter of 143 m: rectangle with width of 11 which of the following equations can be used to determine the length of the longer side of the rectangle? x + 11 = 143 11x = 143 121x = 143 2x + 22 = 143

The perimeter of a rectangle is defined as the sum of the lengths of its sides.

A rectangle has four sides.

Call "to" the long and "b" the width

Then the 4 sides of a rectangle are

a + a + b + b.

This means that the perimeter "P" of a rectangle is defined as:

We already know the perimeter P = 143 and the length of one of its sides that is a = 11

Then the perimeter equation of this rectangle is:

Therefore the answer is the last option

2x + 22 = 143

Explanation:

Although the statement is miswriten, it can be infered that the rectangle has these dimensions:

The perimeter is the length of the four sides, which is given by the formula:

Now substitute the dimensions given and simplify until getting some of the equations of the choices:
