The side length of a square is represented by the expressions n-1.5

Sagot :

solution

We know that the length is given by l = n-1.5

And the perimeter is given by:

P = 4l

Where P= perimeter an dl = side of the length

So then we have:

P = 4(n-1.5) = 4n -6

And the possible equivalent expressionas are:

a) n+n+n+n -1.5-1.5-1.5-1.5 = 4n -6

c) 2(n-1.5) + 2(n-1.5) = 2n -3 +2n -3 = 4n -6

d) 4(n-1.5) = 4n -6
