10cm2
The area of a rectangle is given by the formula: length x width. So, for the textbook, the area would be 5cm x 2cm = 10 square cm.
If Length * Width = Area, then Area ÷ width = Length
Area = (length) times (width)Length = (area) divided by (width)Width = (area) divided by (length)
For a rectangle, area equals length times width. To find the length given the width and area, divide the area by the width.
To find the relationship in width and area you can use the formula area/length = width. To find the area of a room you multiple the length by the width.
Width * Length = Area so..... Width = Area / Length
Find the width, and multiply the length and the width.
For a rectangle or square, Area = Length * Width So Length = Area / Width.
Length and Width. Area = Length * Width
Area divided by width equals length
you need length and width length multiply width = area length + length + width + width = perimeter
divide area by width and voila! u get the length
Divide area by length and that gives you width.
