If the perimeter of a rectangle is 18 inches and one side is one inch shorter than the other how long are the sides

Start with appropriate representations:  L = length and W = width.  Then W = L - 1.

The perimeter is P = 18 in = 2L + 2W, which here would be:

                                  18 in = 2L + 2(L - 1), or   18 in = 4L -2.  Solving for L:

                                                                         20 in = 4L, and L = 5 in.

Then W = 5 in - 1 in = 4 in.

Note that 2W + 2L does come to 18 in here:  2(5 in) + 2(4in) = 18 in.

The side lengths are 4 and 5 inches, respectively.

i use my brain for prombles like this maybe you could try it

step-by-step explanation:

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
