The area of an aerobics floor is 3,200 square meters. What is the area if the length and width are doubled?

a.6400

b.9600

c.12,800

d.25,600

The area of an aerobics floor if the length and width are doubled = 12800

Step-by-step explanation:

Given -

The area of an aerobics floor is 3,200 square meters.

Let x and y be the lenth and width of aerobics floor

then

 = 3200

y =

the area if the length and width are doubled .

then

length = 2x  and width = 2y

area of an aerobics floor =

                                          = 4xy

putting the value of y

area of an aerobics floor =

                                           =

                                           = 12800

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
