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

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.
