The net shows an equilateral triangle with side length 24 cm.
The area of an equilateral triangle of side length s is ...
... A = (√3)/4·s²
Using the above side length, the area is
... A = (√3)/4·(24 cm)² = 144√3 cm² ≈ 249.4 cm²
Your best choice is the first one:
... A) 249.6 cm²
Answer:
31
Step-by-step explanation:
Here the trick is to perform the indicated operations in the correct order. Anything inside parentheses must be done first, followed by any multiplication or division, followed by any addition or subtraction.
Doing the work inside parentheses first:
(3 × 22) ÷ 6 + [28 – (4)2] => (66) ÷ 6 + [28 - 8], or
(66) ÷ 6 + [28 - 8] => 11 + [20], or 31
You take 500,00,00 divided that by 400 and you get your answer 12,500
Answer:
432 tiles
Step-by-step explanation:
First, convert the dimensions of the table to inches.
There are 12 inches in a foot, so multiply 1.5 and 2 by 12.
1.5(12) = 18
2(12) = 24
So, the dimensions of the table in inches are 18 by 24.
Find the area of the table using the formula, A = lw
A = lw
A = (18)(24)
A = 432
So, the area is 432 square inches.
Since each tile is one square inch, the table will fit 432 of these.
So, Ravi will need 432 tiles.
