Step-by-step explanation:
Scale Factor of UVW to XYZ
= XY/UV = YZ/VW = XZ/UW
= 21/3 = 28/4 = 14/2
= 7. (B)
Answer: 105
Step-by-step explanation:
Corresponding sides of similar triangles are proportional, so

A² + b² = c²
8² + x² = 16²
x² = 16² - 8²
x² = 192
x =√192
x =8√3
The first thing we must do is find the amount of land that will be used for the 120 lots.
We must remember that 10% of the land will not be used for the lots.
We have then:

Then, we must consider the following conversion of units:

Applying the conversion we have:

Then, the amount of square feet for each lot is given by:
Answer:
There will be 32670 square feet in each lot.
