If both diagonals are 10 units then the rhombus is, in fact, a square. Its area is 50 square units.
Find the area of a rhombs with diagonals that measure 8 and 10.
Area of the rhombus: 0.5*8*10 = 40 square feet
60 square units.
Area of a rhombus= 1/2 (d₁) (d₂); where, d₁ and d₂ are the diagonals. Solution: A=1/2 (10) (12) = 60 feet²
The diagonals of a rhombus cannot be the same size.
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.
60 feet
The area of rhombus with diagonals 28Cm square and 28Cm is: 392 cm2
40 sq feet
If those are its diagonals then area is: 0.5*10*11 = 55 square units other wise use Pythagoras to find diagonal EG because area of a rhombus is 0.5 times the product of its diagonals.
If 10 and 11 are its diagonals then its area is: 0.5*10*11 = 55 square units
If this is a rhombus then the area is half the product of the diagonals - 10 x 14 = 140. Half of 140 = 70, so the area is 70 square feet.
