Surface areas are measured in square units, such as square inches, square feet, square meters, etc. To determine the surface area, first ensure you have the length and width of the rectangle expressed in the same units (both in inches, both in feet, etc.), then multiply the length by the width: 2 feet x 3 feet = 6 square feet

That gives you the surface area.That gives you the surface area.That gives you the surface area.That gives you the surface area.
if 3x4 is dimension of rectangle and 5 is the altitude, then, 49.035 sq. units is its surface area
314 square inches in total
Area of a rectangular prism = 2lw + 2lh + 2wh, where l is length, w is width, and h is height.
Area of a rectangle = length x width

rectangle
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
Surface area = length*width in square units
Multiply the length by the width. If the rectangle is a square the two dimensions will be the same
You need two dimensions to calculate the area of a rectangle. Area = length multiplied by width.
Length x Width x Height = surface area
Surface area of rectangle: 15 times 8 = 120 square inches
actually surface area is always of 3 -d figures not for 2 d figures. area of rectangle= length x breadth.. remember never use surface area term for 2d figures. :)
