I'm in grade 5 and I need help on an area and perimeter question. The area of a rectangle is 300mm and the length of it is 15 mm. I need to find out the width of this rectangle.
What don't you understand about my previous answer to your question?

To find the width of the rectangle, you'll need to use the formula for the area of a rectangle:
Area = length × width
You are given the area of the rectangle, which is 300mm, and the length, which is 15mm.
To find the width, you can rearrange the formula as follows:
Width = Area / Length
Now you can plug in the given values:
Width = 300mm / 15mm
To divide 300mm by 15mm, you simply divide the number 300 by the number 15.
300 ÷ 15 = 20
So, the width of the rectangle is 20 mm.
