Answer:

l = 63 in

Step-by-step explanation: If the P=150 in W=12 in so .... using the formula P=2 (l + w) you get L= P/2 - W = 150/2 - 12 = 63 in. I hope this helps!

Answer:

63 inches

Explanation:

The perimeter of a rectangle is found by adding all of the side lengths. Since both pairs of opposite sides have the same length, an equation for the perimeter can be written like this:


P=2w+2l

Where w and l represent the width and length.

Since we are asked to find the length, rewrite the equation in terms of l:


l=(P-2w)/(2)

We know the values for P and w, so plug those in:


l=(150-2(12))/(2)

Now simplify!


l=(126)/(2)=63
