Answer:
1) 90
2) 38
Step-by-step explanation:
1) look at the attached diagram
As you can see, the floor and the wall must meet at a 90° angle.
2) Perimeter of office: 10 + 12 + 10 + 12 = 44
Subtract the door and windows' lengths:
44 - 3 - 3 = 38 ft.
Your answer would be 22a4b4 the 2 is sqr and 4s are sqrt
Answer:
PR = 5 because LP + PR = LR according to the Segment Addition Postulate, and 7 + 5 = 12 using substitution
Step-by-step explanation:
The naming of the segments suggests that point P is between L and R, so that ...
LP + PR = LR
This corresponds to the last choice.
_____
<em>Comments on the alternate interpretation</em>
On the other hand, if point L is between P and R, then the segments are PL and LR. The Segment Addition Postulate would tell you that ...
PL + LR = PR
The Reflexive Property of Congruence would tell you that PL = LP. The Substitution Property would tell you LP can be substituted into this equation, making it ...
LP + LR = PR
and by the commutative property, ...
LR + LP = PR.
Multiple properties of addition and congruence are involved with this interpretation, which more or less matches the third choice. That is, the simple explanation of answer choice 3, by itself, is insufficient to explain why the length of PR should be considered to be 19, not 5.
We must remember the equation to find the area of a trapezoid first.
Area =

A and B are the bases (6 and 12)
The height is 6 for each trapezoid
Now Solve!
====================================================================
SOLVING...
Area =

Area =

Area = 9 * 6
Area = 54
Since there are two trapezoids, multiply 54 by 2
54 x 2 = 108
Area = 108
