Answer:

l = 10.5 cm and A = 21 cm2

Step-by-step explanation:

Area is w*l

Perimeter is 2(w+l)

Replacing the information known in the problem you can get the length with the perimeter

P = 2(w+l)

25 = 2(2+l)

12.5 = 2 + l

10.5 cm = l

with the length now you can find the area

A = w*l

A = 2*10.5

A = 21 cm2

Tell whether the situation should be represented by a continuous graph or a discrete graph.
Fittoniya [83]
For the book store, it is a discreet graph. Every book is a case by itself, no event is dependent on the other. So now variable is dependent on another.
The swimming pool case, the time is the independent variable in the function where the water volume changes with respect to time. So it it has a continuous graph.

Hope this helps.

natulia [17]

Answer:

The ratio of the length of the banner to the length of the sign = 54/17

So....since they are similiar figures, the widths will have the same ratio

And the ratio of the area of the banner to the area of the sign will be the square of this ratio  

Step-by-step explanation:

[54/17]^2  = 2916/289
