ANSWER PLEASE OR EXPLAIN . i would appreciate it a lot . Find the percent of change. Where necessary, round to the nearest percent. Describe the percent of change as a percent of increase or decrease.

31 in. to 7 in.

A. 77%; percent of increase

B. 77%; percent of decrease

C. 23%; percent of decrease

D. 23%; percent of increase

C.

Step-by-step explanation:

so what i think they are asking is how much more would you have to add to the percentage of 31% to get to 7% and to do that you must decrease the percentage by 23% to get 7. I hope this helps❤

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .
