Question

Perimeter of rohmbus is 100 one of its dignol is 40 find the area

Answer 1

Diagonals of a rhombus are perpendicular bisectors of each other.Continued …correction 25^2 = 20^2+ OD^2625= 400+OD^2625 - 400 = OD^2225 = OD^2OD= + or - 15 ( Taking square root on both sides).Discarding the negative sign , length of OC = 15 cmDO+ OB = DB15+ 15 = DB30 cm is length of diagonal DBArea of a rhombus is (1/2)*product of two diagonalsArea =( 1/2)*40*30= 1200/2 = 600 .Ans : 600 672 Views · Answer requested by Area of rhombus will be 600 cm^2.
