Unit rate means how much does it cost for 1 item for example...if you can download 2 songs for $5 how much did it cost to download 1 song...you would simply take $5 divided by 2 to get $2.50

In this case we have 5 yards of fabric for $18 so all we have to do is take $18 divided by 5 to find out how much just 1 yard costs.

so $18 divided by 5 is $3.60  so the unit rate cost per yard is $3.60 

to make sure this is correct you can check your answer like this.  If it is $3.60 for 1 yard how much would it be for 5 yards?  Multiply $3.60 and 5 if we get $18 then our answer is correct.  $3.60 x 5 does equal $18 so we were correct

How do you calculate the area and the perimeter of a parallelogram and a triangle?
Mnenie [13.5K]

for parallelograms:

area = b(h)

so basically, the length times the height. just like how you would find the area of a square.

perimeter: just add all of the sides together.

for triangles:

area = 1/2(b) x h

so half the length multiplied by the height. for example, if the length was 4, you have to use half of that. so that means 2 times whatever the height is.

perimeter: again, just add all three sides together
