Question

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

Group of answer choices


a. S = 1/2p - L

b. S = 1/2p+L

c . S=1/2p+2L

d. S = 1/2p-2L

Answer 1

The answer is A

A. S = 1/2p - L

Explanation:

Step one:

given the perimeter function

P = 2S + 2L

we are expected in this problem to change the subject of the formula to S

Step two:

firstly, let us isolate the term that has S

2S=P-2L

divide both sides by 2

2S/2= (P-2L)/2

S=P/2-L

S = 1/2p - L
