Arectangle's width is 6 feet less than its length. if the area of the rectangle is 247 square feet, what is its length, in feet?

Length is 19 feet.

Width is 13 feet.

Step-by-step explanation:

Let the length of the rectangle be = L feet

The width is 6 feet less than its length, so width is = L-6 feet

The area of the rectangle is 247 square feet, means length x width = 247

Now here a = 1, b = -6 and c = -247

So, putting these in quadratic equation formula, we get

This gives L=19 or -13

As it is a dimension, so we will neglect the negative value.

Hence, L = 19 feet

Width = = 13 feet

you divide the cost ($15) by the quantity (6) to get your questions answer. the yo-yo costs $2.50. hope this : )!
