3. a sign company is building a sign with the dimensions shown. what is the area, in square feet, of the sign? round to the nearest foot. justify your answer by showing your work. (5 points)

84.87sq ft

Step-by-step explanation:

Let ABC be the triangle and  AD be the perpendicular on BC such that BD=DC=7ft.

Now, it is known that

Now, in triangle ADC, we have

Now, area of the triangle=

=

=

Thus, area of the building is 84.87sq ft.

the answer is 5636.7

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
