The length of a rectangle is 4 more than the width. Find the width of the rectangle if the area is 32.
Serggg [28]

Answer:

length = 8

width = 4

Step-by-step explanation:

Area = length x breadth

Let x represent the width

length = x + 4

32 = x × (x + 4)

32 = x² + 4x

x² + 4x  - 32  = 0

solving using quadratic equation =

(x² - 4x) -32 + 8x

x = 4 or -8

since width cannot be a negative number, we would use 4

Ronch [10]
The perimeter = 2 length + 2 width 

the length = the width +47

314 = 2*(w+47) +2w

314 = 2w +94 +2w

220 =4w

w= 220/4 = 55

l = 55+47 = 102

the length = 102 ft

the width = 55 ft
