The two numbers that multiply to 24 and add up to 11 are 3 and 8. When you multiply them, 3 × 8 = 24, and when you add them, 3 + 8 = 11.
The two numbers that multiply to 24 and add up to -11 are -3 and -8. When multiplied, -3 × -8 equals 24, and when added, -3 + -8 equals -11.
11 multiplied by 24 is 264.

I believe it is 1 and 19/24ths. I am not sure, but I will explain so you can check my math. First I found the common denominator, which is 24, then multiplied the top number by what I multiplied the bottom number by. For the 7/8 I multiplied by 3, which came out to be 21/24, and I multiplied the 11/12 by 2, which comes out to 22/24. If you add those up, you will get 43/24. Then, all you have to do is simplify.
I multiplied get answer -3

You have to find two numbers that when multiplied together equal 24 and when added together equal 11. The numbers are 1 x 24 = 24 (1 + 24 = 25); 2 x 12 - 24 (2 + 12 = 14); 3 x 8 = 24 (3 + 8 = 11). The recangle is 3 tiles wide by 8 tiles long.
To find the number, we can divide 24 by 0.12. The result is 200, so the number that when multiplied by 0.12 gives the product 24 is 200.
