Answer:
The area of the rectangle ABCD is 
square units.
Step-by-step explanation:
From statement we have that rectangle ABCD is formed by the following points: 
. First, we calculate the length of each side by the Pythagorean Theorem:
Which satisfies all minimum characteristics for a rectangle. The area of the rectangle ABCD is the product of its base and its height, that is:
The area of the rectangle ABCD is square units.
Answer:
day 15
Step-by-step explanation:
13 - 6 miles = 7 miles or 14 one half miles
week1 + 14 weeks = week 15
6 6.5 7 7.5 8 8.5 9 9.5 10 10.5 11 11.5 12 12.5 13
Let M = Mary's age.
Let J = Jo's age
Let L = Larry's age.
The sum of their ages is 120. Therefore
M + J + L = 120 (1)
Mary's age is three times Jo's age. Therefore
M = 3J (2)
Larry's age is 5 less than Jo's age. Therefore
L = J - 5 (3)
Substitute (2) and (3) into (1).
3J + J + (J-5) = 120
3J + J + J - 5 = 120
5J - 5 = 120
5J = 120 + 5 = 125
J = 125/5 = 25
Therefore
J = 25, M = 3J = 75, L = J - 5 = 20
Answer: Mary's age = 75; Jo's age = 25; Larry's age = 20
If Mary's age is 75, then Jo's age is 25, and Larry's age is 20.
