Question

the perimeter of the Rhombus is 280 cm and the height is 10 centimetre if one diagonal is 0.20 metre find length of other diagonal in metre

Answer 1

Side of rhombus = 280/4=70

Area = base(side) ×height

A=70×10 =700sq cm

We know

Area = 1/2×d1×d2 =700

d2 = 1400/d1

d2 = 1400/20

d2 = 70 cm

Other diagonal is 70 cm long
