Answer: length in terms of P=2(l+b) is,
L=P/2-B
Step-by-step explanation: We will have to start by bringing L on the one side of the equations away from the other factors.\
1. We will Divide both the sides of the equation by 2 to distant the term (L + B):
P/2 = (L + B).
2. Then we will Subtract B from both sides of the equation to isolate the term L:
P/2 - B= L
Therefore, the solution for L in terms of P, B, and the equation P = 2(L+ B) is:
L= P/2 - B
