1.) a square has a perimeter of 144 yd. what is the length of each side

2.) a square has an area of 4 ft^2 . what is the length of each side?

1) 36 yard

2) 2 feet

Step-by-step explanation:

1) Perimeter = 4 * side length

  144 = 4 * s

  s = 36

2) Area = Length * Length

   4 = l * l

   l = 2

step-by-step explanation:

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
