Question

A rectangular field is 5 feet longer than it is wide, its area if 374ft^2. Use a calculator. Rounding anwsers to the nearst hundreth.
a. write an equation that represents this information
b. find the length and width of the field

Answer 1

Answer:

Equation is x²-5x-374 = 0

L = 13, B = 8

Step-by-step explanation:

Let x be length of the field

Width will be x-5

Now area = l*w = x *(x-5) =374

x²-5x =374

Converting it into a quadratic equation:

x² -5x -374 = 0

(x-13)(x+8) = 0

Since x can't be -ve so x = 13

Width or Breadth = L-5 = 8
