If they are 2.5 inches tall and the back splash is 2.5 feet tall that means you can fit 12 tiles vertically.
6 inches is 1/2 of a foot so 16 tiles can fit horizontally in 8 feet.
12 x 16 = 192
Final answer:
192 tiles
Hope I helped :)
You can split this into 2 shapes.
1 of the shapes will be a small square. The dimensions for it would be 4 by 3 (12)
The second shape, the bigger rectangle has the dimensions, 12 by 6 (72)
Now add these two values 12+72 and you get, 84
you answer is A 84 square inches
Step-by-step explanation:
k = √(49 - 12√5)
= √(45 + 4 - 2 √180)
= √45 - √4
= 3 √5 - 2.
<em>So, k + 2 = 3 √5 - 2 + 2 = 3 √5.</em>
