Thank you to whoever answers this!

A) width = 8  in  , length =24  in

B) area = 192  in^2

Step-by-step explanation:

the perimeter of the rectangle is 64 in

length = 3 * width

A) find the length and the width

B) find the area of the rectangle

formula:

2* (length + width)

we can give variable :

length = l  and width = w

l = 3w

place this into the formula:

2* (3w + w) = 64

2 * (4w) = 64

8w = 64

w = 64/8

w = 8 in

place the value of w into the formula

l = 3w

l = 3*(8)

l = 24 in

formula:

length * width

place the values of length (l) and width (w) into the formula:

8 * 24

=192  in^2

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
