8 ft.
The area of the rhombus is 40 square feet. To see why, Draw a rectangle encompassing the rhombus with sides parallel to the rhombus' diagonals. The rectangle has dimensions 10 ft X 8 ft = 80 square ft. Using the diagonals as dividers, each quarter of the rectangle is divided into 2 by one of the rhombus' sides. Thus the area of the rhombus is exactly half that of the encompassing rectangle.
To find the area of a rectangle, you multiply the length by the width. In this case, the length is 3 feet and the width is 8 feet. Therefore, the area of a rectangle with a length of 3 feet and a width of 8 feet is 24 square feet (3 ft x 8 ft = 24 sq ft).
Multiply your length by your width 8 ft x 4 ft = 32 square feet
