Answer:
Perimeter = 46.6 m
Area = 78.36 m²
Step-by-step explanation:
Perimeter is just the outsides, so add 3.7 + 12.3 + 4.5 +11 AND the sides you aren't given. To find them, you do 11-3.7 = 7.3 and 12.3-4.5 = 7.8. So you add 3.7 + 12.3 + 4.5 + 11 + 7.3 + 7.8 = 46.6
Area is the inside, so you multiply length by width. You can split it different ways, but I multiplied by 3.7*12.3 first, giving 45.51. Now to find the area of the other box, you need to subtract 11 by 3.7, which we saw was 7.3. Now we can multiply 7.3 by 4.5, which is 32.85. Then you add 45.51 and 32.85 to get 78.36.
The length of the room is 16 feet long.
Answer:
Step-by-step explanation:
Assuming this is a linear equation in the form of 
, we can first solve for the slope using 
, for these points, the slope would be 
. Now we plug in the points to get the equation:
plugging in (7,5), we get 
×
+ 
and solving for b, we get b = 
therefore, the equation of the line passing through (7,5) and (1,2) is .
hope this helps!
