What does 5 less than 3 times mean? I need help badly it’s due tomorrow for Algebra 1.

HERES THE FULL QUESTION: The width of a rectangle is five less than three times the length of the rectangle if the perimeter of the rectangle is 70 inches what are the dimensions of the rectangle?

Sagot :

MrRoyal

The dimensions of the rectangle are 10 inches by 25 inches

How to the dimensions of the rectangle?

The given parameters are

  • Width = five less than three times the length
  • The perimeter of the rectangle = 70

The above parameters mean

w = 3l - 5

P = 70

The perimeter of the rectangle is

P =2(l + w)

So, we have

2(l + 3l - 5) = 70

Divide by 2

l + 3l - 5 = 35

Evaluate the like terms

4l = 40

Divide by 4

l = 10

Substitute l = 10 in w = 3l - 5

w = 3 * 10 - 5

w = 25

Hence, the dimensions of the rectangle are 10 inches by 25 inches
