20-13=7, 21-12=9, 7*9=63; 20*12=240; ANSWER: 63+240=303
Answer:
The answer to your question is shortest ladder = 6 ft, middle ladder = 12 ft, longest ladder = 24 ft.
Step-by-step explanation:
Data
Ladder 1 = x/2
Ladder 2 = x
Ladder 3 = 2x
Total length = 42 ft
Process
1.- Sum the length of all ladders and solve for x
x/2 + x + 2x = 42
Least common factor = 2
(x + 2x + 4x)/2 = 42
Simplify
7x/2 = 42
7x = 42(2)
7x = 84
x = 84/7
x = 12
2.- Find the length of the ladders
Ladder 1 = 12/2 = 6
Ladder 2 = 12
Ladder 3 = 24
