Question

A square has a perimeter of 38 inches we want to know the length of each side? Chose the best model for this problem. (Side length above perimeter four times) (perimeter above length and width) (Side length above perimeter twice) (perimeter above side length four times).

Answer 1

perimeter above side length four times

Explanation:

we know that

The perimeter of a square is equal to

`P=4b`

where

b is the length side of the square

Solve the formula by b

That means----> isolate the variable b

Divide by 4 both sides

`b=(P)/(4)`

we have

`P=38\ in`

substitute

`b=(38)/(4)=9.5\ in`

Rewrite the expression
`b=(P)/(4)`

`(P)/(b)=4`

so

perimeter above side length four times
