Softa [21]
Hi there!

We'll be finding the area of the entire middle rectangle (the big one), since that is the lateral area. It has a height of 15 and a length of 18.

15 x 18 = 270

The correct answer is the first option, 270m^2.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

A new pair of shoes is advertised for $110. The sales tax is 7.5%. What is the total cost of the shoes?
CaHeK987 [17]

Answer:

$118.25

Step-by-step explanation:

Always convert the percentage to a decimal by moving the decimal two points to the right/dividing by 100. So 7.5 % = 0.075

110 x 0.075 = 8.25 (the amount of tax added)

110 + 8.25 = 118.25

You can also multiply 110 by 1.075, where the "1" is the $110 and the ".075" is the tax, and save the step of adding. 110 x 1.075 = 118.25
