Answer:
- area 170 in²
- perimeter 78 in
Step-by-step explanation:
The Pythagorean theorem tells you the long side (x) of the rectangle is found from ...
5² + x² = 34.37²
25 + x² = 1181
x = √(1181 -25) = 34
The rectangle is 5 inches wide and 34 inches long.
The area is the product of the length and width:
area = (34 in)(5 in) = 170 in²
The perimeter is twice the sum of length and width:
perimeter = 2(34 in + 5 in) = 78 in

Answer:
B) She is incorrect because when substituting 2 for m the result was a false statement.
Step-by-step explanation:
Let's solve it for ourselves and see if Mia is correct:
7.8+2(0.75m+0.4)=-6.4m+4(0.5m-0.8)
7.8+1.5m+0.8=-6.4m+2m-3.2
1.5m+8.6=-4.4m-3.2
8.6=-5.9m-3.2
11.8=-5.9m
-2=m
m=-2
Since the answer is actually m=-2, Mia's guess is incorrect because plugging in m=2 does not make both sides equal. Therefore B is the correct option.
