The perimeter of rectangle is 294 cm. the width is 57 cm. find the length.

The perimeter of a rectangle is length + length + width + width (also know as the distance around the whole shape) so an equation like this can be written:

294 = 57 + 57 + 2l (as in the length times two, or length + length)

294 = 114 + 2l

180 = 2l

90 = l

So the length of this rectangle is 90

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

the answer is d
