You are knitting a blanket. You want the area of the blanket to be 24 ft.sq. You want the length of the blanket to be 2 feet longer than is width. What should the dimensions of the blanket be?

Blanket is a rectangle.
Let width be x feet
So length is x + 2 feet
Area of rectangle is length * breadth
So,
24 = x*(x+2)
x^2 + 2x 24 = 0
X^2 + 6x – 4x 24 = 0
X(x + 6) – 4(x + 6) = 0
(x4)(x+6) = 0
Therefore x = 4,6
Since breadth can’t be negative, x= 4
Which means length = 6

width – 4 ft
length – 6 ft
6 x 4 = 24
