Question

The reading rug in Mrs. Shaw's room has a perimeter of 28 meters. The table gives the length and width of the rug.

If the equation 4(x+3.3)=28 can be used to find the perimeter of the rug, what is the value of x? Write your answer as a decimal to the nearest tenth.

Answer 1

4 (x + 3.3) = 28

Distribute the 4:

4x + 13.2 = 28

Subtract 13.2 to both sides:

4x = 14.8

Divide by 4 on both sides:

x = 3.7
