Answer 1

Answer:4515

Step-by-step explanation:Area of square=s*s

Then total area of 14 squares is 11^2+12^2+......23^2+24^2 is sum of square of first 24 natural numbers - sum of square of first 10 natural numbers

Sum of first n square natural numbers = (n(n+1)(2n+1))÷6

Sum of first 24 square natural numbers =4900

Sum of first 10 square natural numbers=385

=4900-385=4515
