What is the area of a rhombus whose side is 30 cm and one diagonal is 40 cm?
The diagonals of a rhombus are perpendicular bisectors of each other. Use the Pythagorean Theorem and one of the right triangles to solve for x.
302=202+x2
x2=500
x=105–√
One of the formulas for the area of a rhombus is A=12d1d2
A=12(40)(205–√)=4005–√cm2
orA≈894.427191cm2
