The perimeter of a rectangular field is 60 m. What are three possible measurements
of the field? Use dimensions to the
nearest meter.

10m by 20m

12 m by 18 m

14m by 16m

Step-by-step explanation:

The perimeter of a rectangle is

P = 2(l+w)

60 = 2(l+w)

Divide each side by 2

30 = l+w

Let l = 10

Then w = 30 - 10 = 20

Let l = 12  then w = 30 - 12 = 18

Let l = 14  then w = 30 -14 = 16

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!
