Jonh is building a stage for a school play. The stage is 15 1/2 feet long and 20 feet wide. Select ALL options that represent the area of the stage, in square feet. A. 31/2 X 1/20B. 30/2 X 20 C. 31/2 X 20D. 300E. 310

Respuesta :

To solve this problem, recall that the area of a rectangle is given by the following formula:

[tex]A=wide\times length.[/tex]

Therefore, the area of the stage is:

[tex](15\frac{1}{2}\times20)ft^2.[/tex]

Converting the mixed number to an improper fraction, you get:

[tex]15\frac{1}{2}\times20=\frac{31}{2}\times20.[/tex]

Computing the multiplication you get:

[tex]310.[/tex]

Answer:

[tex]310,\frac{31}{2}\times20.[/tex]
