<h3>What is a 2-digit number?</h3>
A digit is the whole numbers from 0 to 9 and the arabic numerals representing them, which are combined to represent base-ten numbers.
A 2-digit number is any number between 10 and 99.
According to this question, 994 is said to be added to a 2 digit number to result into either 1001, 1002 or 1004.
- 1001 - 994 = 7 (1 digit)
- 1002 - 994 = 8 (1 digit)
- 1004 - 994 = 10 (2 digit)
Therefore, the number that will be the sum of 994 and a 2 digit number is 1004.

The breadth of rectangle in one third of length and perimeter is 80 find the length.
The giraffe (using the ruler) is 11 cm.
1 cm : 50 cm
Multiply both sides by 11.
11 cm : 550 cm
There are 0.01 meters in 1 centimeter.
Multiply 550 cm by 0.01.
(550)(0.01) = 5.5
The giraffe's real length is 5.5 meters.
