One side of a rectangle is 4 feet shorter than four times the other side. find the sides of the are if the rectangle is 24 square feet

The first side of the rectangle  =  3 ft

The other side =  8 ft

Step-by-step explanation:

Let the one side of the rectangle  = k feet

So, the other side of the rectangle = 4 ( First side) -4  =  (4 k -4 ) ft

Now, the area of the given same rectangle  = 24 sq ft

Area of the RECTANGLE = LENGTH x WIDTH

⇒ Area  = k x ( 4k - 4)

or, k ( 4k - 4)  = 24

or, k(k-3) +2(k-3) = 0

or, (k-3)(k+2) = 0

or, k = 3, or k = -2

As k = Length of the rectangle, so CAN NOT BE NEGATIVE.

⇒ k ≠ -2 , ⇒ k = 3 ft

So, the first side of the rectangle  = k =  3 ft

The other side = 4 k - 4   =  4 (3) - 4 = 12 - 4 =  8 ft
