If so then it is not rational Square root of 2 is irrational and any number formed by multiplying or dividing it by a rational number is also irrational.
Let the number of rows be x
rows = x
seats in each row = x + 20
total seats = 1344
x (x + 20) = 1344
x^2 + 20x - 1344 = 0
(x + 48)(x - 28) = 0
x = -48 (rejected, answer cannot be negative) or x = 28
Therefore,
x = 28
x + 20 = 48
Check:
Row = 28
Numbers of seat per row = 28 + 20 = 48
28 x 48 = 1344 (Correct)
Ans:There are 48 seats per row
Step-by-step explanation:
$480 is 40% off the original price
=> $480 is 60% of the original price
Hence the original price is $480 * (100/60) = $800.

Answer:
180 cm
Step-by-step explanation:
2(3*10) = 60
3*12 = 24
1/2(12*8) * 2 = 96
