Answer:
B) 171 units^2
Step-by-step explanation:
The area is given by the formula ...
A = 1/2(b1 +b2)h
Filling in the given base and height values, we find the area to be ...
A = 1/2(23 +15)(9) = (19)(9) = 171 . . . square units

<em>Additional comment</em>
You can select the correct answer choice simply on the basis of "reasonableness." If this were a 9×15 rectangle, its area would be 9×15 = 135 square units, more than 85.5. You know its area is less than a 9×23 rectangle, so is less than 9×23 = 207 square units. Only one answer choice is a value between 135 and 207.

Multiplication by 9 is not so hard. It is multiplication by 10-1:
15×9 = 15×(10 -1) = 150 -15 = 135
10 * $1 = $ 10
$10 / 10 = 1

pretty simple
Answer:
The answer to your question is length = 24 ft
Step-by-step explanation:
Data
Rectangular-shaped
Area = 360 ft²
lenght = x
width = 5/8x
Formula
Area = length x width
- Substitution
360 = (x)(5/8x)
- Solve for x
360 = 5/8x²
x² = 360(8)/5
x² = 2880 / 5
x² = 576
- Result
x = 24 ft
- Conclusion
The length of the living room is 24 ft and the width is 24(5/8) = 15 ft.
