Q:
# A square plywood platform has a perimeter that is 6 times the length of a side, decreased by 6. Find the length of a side. (Recall the formula P = 4s.) a. 5 c. 3 b. 1 d. 2

Accepted Solution

A:

The platform is square. Let the length of one side be x.

Then the perimeter is P = 6x - 6 = 4x

Then 2x = 6 and x = 3. The side length is 3.

Check: P = 4(3) = 12

P = 6(3)-6 = 12

These agree.

Then the perimeter is P = 6x - 6 = 4x

Then 2x = 6 and x = 3. The side length is 3.

Check: P = 4(3) = 12

P = 6(3)-6 = 12

These agree.
