How do you find the percent change from 84 to 63?

25% Change

Step-by-step explanation: To find the percent change from 84 to 63, we will be using the "percent change" equation.

change = percent change x actual

To find the change subtract 63 from 84. 84 - 63 = 21. So the change is 21.

21 = percent change x actual

The actual is 84, because 84 is your original amount.

21 = percent change x 84  (Solve for p, percent change.)

21 = p x 84

21/84 = p

0.25 = p

Now, multiply the decimal 0.25 by 100 to get the percent change.

0.25 x 100 = 25, Or a 25% change.

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
