Answer:
The length of the first banner = 8 ft
The length of the second banner = 12 ft
The length of the third banner = 16 ft
Step-by-step explanation:
The total length of the banner material = 36 ft
Now, let us assume the length of the first banner = k ft
So, the length of the second banner = First banner + 4 ft = ( k + 4) ft
The length of the third banner = Second banner + 4 ft = [( k + 4) + 4] ft
Now, according to the question:
The length of ( First + Second + Third) banner = 36 ft
⇒ (k) + (k +4) + (k + 8) = 36
or, 3 k = 36 - 12= 24
or, k = 24/3 = 8
⇒ k = 8 ft
So, the length of the first banner = k = 8 ft
The length of the second banner = k + 4 = 8 + 4 = 12 ft
The length of the third banner = k + 4 + 4 = 8 + 8 = 16 ft
