Respuesta :

Answer:

$825869.52

Step-by-step explanation:

Given that,

Width of the rectangle, b = 42 ft

Length of the rectangle, l = 25.5 ft

The area of a rectangle is given by :

A = lb

So,

A = 42 ft × 25.5 ft

A = 1071 ft²

The total cost of the wallpaper was $771.12 . So,

Cost = 1071 × 771.12

= $825869.52

So, the cost of wallpaper per square foot is equal to $825869.52.
