The area of a rectangle is 123 cm2. If the width is 3 cm, find the length. Let l represent the length of the rectangle.
Answers
Answer:
41 cm
Step-by-step explanation:
123/3
The formula for the area (A) of a rectangle is given by A = l * w, where l is the length and w is the width. We are asked to find the length and we are given the width (3 cm) and the area (123 cm2).
To find the length, we need to manipulate this formula to solve for l. So, divide both sides of the equation by w, this gives us: l = A / w.
We now substitute the given values into this equation:
l = 123 / 3
This simplifies to:
l = 41.0
So, the length of the rectangle is 41.0 cm.

means what number should we add to 273 to obtain 400.
To find that number, we subtract 273 from 400.
To do that we need to set up the numbers as below to make the calculation easy for us.
We do the subtraction from right to left.
The first digits are 0 and 3. Since 0 is less than 3, we 'borrow' from the next digit.
But sad for us, the next digit to the right is also zero. So we borrow from the from the first non-zero digit which is 4.
Borrowing 1 from 4 makes the hundred digit reduce to 3. Since we are operating in base 10, the 1 we borrow has a value of 10. Adding that 10 to the zero at the immediate right of 4 makes it 10. Now we can borrow one from this "10". That makes it become 9. That is why you are seeing '39' at the top of the '40'. Now our right mist zero has a value of 10(written at the topmost right).
We subtract 3 from 10 now to get 7.
Then 7 from 9 to get 2.
and 2 from 3 to get 1.
Hence
The difference between,
400 and 273 is 127.
The difference between 400 and 273 is 127
The given numbers are,
400 and 273
The difference between 400 and 273 is calculated by subtracting the smaller number from the larger number. So,
400 - 273 = 127.
Now take a creative approach to solve it,
Imagine you have a basket of 400 apples, and a friend takes away 273 apples. How many apples do you have left?
Simply subtract:
400 - 273 = 127.
Or simply
4 0 0
- 2 7 3
__________
1 2 7
___________
So, the difference between 400 and 273 is 127 apples.
