4 goes into 20 5 times,
so you have 1/5 if you reduced it
1/5 is .20 or 20%
to check your work or for an easy way to do it, 1 divided by 5 or 4 divided by 20 which is also .20 or 20%
175 divide by 25 should be 7
then using 80 divide by 40 is 2
7+2=9
then 2 times 40, and 7 times 25, the result is 285
285 divide by 9 get 31.6666......... or 31.7
Answer:
(6,0)
Step-by-step explanation:
Hey there! I'm happy to help!
The perimeter is the distance around the rectangle. You have used the word height, but I will replace it with the word width because the word height is usually used with 3D shapes.
If W is the width and the length is L, the formula for the perimeter is 2W+2L=P.
We can plug in the numbers we already have to solve for L, the length of our base.
2(14.2)+2L=66
28.4+2L=66
We subtract 28.4 from both sides.
2L=37.6
We divide both sides by 2.
L=18.8
The length of the base is 18.8 meters.
Have a wonderful day!
