Question

How would I do this???? Help?
The length of a rectangle is 1ft more than twice its width, and the area of the rectangle is 28ft^2 . Find the dimensions of the rectangle.

Answer 1

Let the width of the rectangle be x
We have the information:
"The length of a rectangle is 1ft more than twice its width,"
Then the length would be 2x+1
Can you try to solve for x?

Answer 2

3x

Answer 3

width=x
and length=2x+1
area of rectangle=lenth*width
x(2x+1)=28
2x^2+x-28=0
or
x^2+1-14=0

Answer 4

sorry x^2+x-14=0

Answer 5

now solve it to get the x

Answer 6

sorry the equation should be 2x^2+x-28=0

Answer 7

width =7 and length=15

Answer 8

sorry width=3.5 and length= 8
