Janice plans to build a rectangular table top with an area of 60+20r square inches. The width of the table top is 10 inches. What is the length of the table top?.
THANK YOU
10(6+2r) = 60+20r
To find the length of the table top, we need to solve for the variable "r" in the given expression for the area of the table top.
The area of a rectangle is given by the formula A = Length * Width.
The formula for the area of the table top in this case is 60 + 20r. We are also given that the width of the table top is 10 inches.
Since the width is given as 10 inches, we can substitute this value into the formula:
60 + 20r = Length * 10
Now, we can isolate the variable "Length" by dividing both sides of the equation by 10:
(60 + 20r) / 10 = Length
Simplifying the equation gives:
6 + 2r = Length
So, the length of the table top is given by the equation Length = 6 + 2r.
