Question

The perimeter of a rectangle is 34 units. Its width is 6.5 units.

Write an equation to determine the length (l) of the rectangle.

Answer 1

Answer: length is 10.5 units. Equation: 34-(6.4*2)

6.5 is one side, so there is two.
34-(6.5*2)= 21
Then divide 21 by 2 because there is two side lengths and you get 10.5.
Overall, 6.6+6.5+10.5+10.5= 34
