Answer:
Option C is correct.
Step-by-step explanation:
Let x be the original width
then x+2 will be the length (consecutive odd integer)
if length is increased by 5 feet , length will be: (x+2)+5 = x+7
Area = 60 square ft.
Area = length * width
60 = (x+7) *x
60 = x^2 +7x
Rearranging
x^2 + 7x -60 = 0
Solving quadratic equation to find the value of x
using Quadratic formula
a=1, b =7, c=-60
Since width can be positive so x=5
length of original rectangle = x+2 = 5+2 =7
Area of original rectangle = Length * Width
Area of original rectangle = 5 * 7
Area of original rectangle = 35 ft^2
So, Option C is correct.
