Answer:
The answer is not in the options, it is 67.5
Step-by-step explanation:
135/2 = 67.5
Let the width be x.
Length: 5"+2x
102=(5+2x)x
102=5x+2x²
0=2x²+5x-102
x=-8.5 or x=6" (I used my graphing calculator to find this)
Since width cannot be negative, the only solution left would be 6. The length would be (5+2(6))=11"
Hope I helped :)
Answer:
assuming you want to cover 18 ft x 15 ft:
18 x 15 = 270 ft²
1.5 x 1.5 = 2.25 ft² per tile
270 ft²/ 2.25 per tile = 120 tiles
