Stella is running a bakery. She has made a street sign to direct people to her bakery. She painted one side of the post and sign. What is the painted area? (Please help I am so confused lol, I am not the brightest -w-)

768 square inches is the correct answer to this problem

Step-by-step explanation:

First we calculate the large rectangle, (75 by 8 in). 75 x 8 = 600

Next we calculate the small square, (12 by 12 in). 12 x 12 = 144

Then we calculate the triangle, (12 by 4 in). [12 x 4]/2 = 24

When you add them all together you get 768 square inches.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
