Question

Carmen measures a room to be `10` `1/2` feet by `12` `5/8` feet. What is the area of the room written as a decimal?

Answer 1

`"Areal "color(brown)( A = 132.56 " sq ft") " (2 dcp")`

Explanation:

Room is in the form of a rectangle and it's area formula is

`A = l * w`

Given : `w = 10(1/2)', l = 12(5/8)'`

`:. A = 12 (5/8) * 10 (1/2) " sq ft"`

`=> (101/8) * (21/2) = (101 * 21) / 16`

`=> 2121 / 16 = color(purple)(132 (9/16) " sq ft"`

`"Area in decimal "color(brown)( A = 132.56 " sq ft") " (2 dcp")`
