The perimeter of a kite can be found using the formula P=2S+2L. Which equation expresses S in terms of P and L?

Answer 1

Hi, you are going to solve the equation in terms of S. When a question asks to "express" a variable in terms of other variables, isolate that variable.

P = 2S + 2L <--------- We want to get S by itself. Let's start by subtracting 2L from both sides.

P - 2L = 2S <--------- Now we need to get rid of the 2 in 2S. Let's divide both sides by 2.

(P - 2L) / 2 = S

The equation above solves for S in terms of P and L.
