Bojangles has a rectangular shaped roof with a width of 6x2 feet and a length 12x3. what is the area of the roof?

432 square feet

or 72*x^5 square feet

Step-by-step explanation:

Let's remember that the formula of the area of a rectangle is A = L*W, where L is the length and W the width.

In this case, L = 12*3 feet and W = 6*2 feet.

With this information,

A = 12*3 feet * 6*2 feet = 432 square feet

A = 432 square feet

But what you wrote can also be interpreted as L = 12*x^3 feet and W = 6*x^2 feet.

In that case, A = 12*x^3 feet * 6*x^2 feet = 72*x^5 square feet

i belive those are the ones that are under 90 degreese.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
