The garage door is 15 feet wide and 6 feet high. it's painted white except for a rectangular panel 1 foot high and 9 feet wide that is brown. how much of the garage door is white

The garage door that is white is:

81 sq feet

Step-by-step explanation:

The garage door is 15 feet wide and 6 feet high.

Area of the door=15×6

                         = 90 sq feet

A rectangular panel 1 foot high and 9 feet wide is brown.

Area that is brown=1×9

                             = 9 sq feet

Area that is white=90-9

                            =81 sq feet

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
