Hey there!

Here's the first one:

This is a pitiful attempt at drawing a rectangle but I think you can get the gist of it, right?

Let x = the width of the rectangle

If the length is 3 more than 2 times its width then, length = 2x +3

2x + 3

_________________

|_________________| x *this is supposed to be a rectangle, i put the equation for the length above it (2x+3)

Perimeter of a rectangle = 2(length) + 2(width)

96 = 2(x) + 2(2x+3)

Solve for x. x is your width, but the question is asking for the length. You can plug your answer for x into the equation for the length and find the length.

Ok? Good luck!!
