Multiply the width times the length.
length*width = area in square units
Area of a rectangle = length x width
Rectangle
rectangle
The base of a rectangle is a length and does not have any area. Therefore, the area can not be calculated.
The surface area is L*B where L is the length of the rectangle and B is the breadth.
Its surface area.
Surface area of a rectangle is length times width
The area of a rectangle is calculated by multiplying the length by the width. The formula for the area of a rectangle is Area = Length x Width.
The area of any rectangle, large or small, is calculated by multiplying length times width.
Surface area = length*width in square units
Length times Height
Multiply the length by the width. If the rectangle is a square the two dimensions will be the same
