Please help me!
(I have already asked the same question twice)

Step-by-step explanation:

Step 1, finding the dimensions:

The width of Stacy's room is x, so the length must be 2x. (Her length of the room is two times the width.)

Her sister's room is 2 yards longer and 3 yards wider than Stacy's room. We have:

Length:

Width:

Great! Let's find the area now.

Step 2, finding the area:

The area of a rectangle is , where l represents the length of the rectangle, and w represents the width of the rectangle. We already know both, so we can plug it in the equation:

We can expand and simplify:

I hope this helps! Let me know if you have any questions :)

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base
