Rhombus is a parallelogram with all sides equal
So perimeter is 4 × side = 140 unit
⇒ side = 140 ÷ 4 = 35 unit
Area of a parallelogram = base × altitude = 35 × altitude = 42 unit
⇒ Altitude = 1.2 unit
So perimeter is 4 × side = 140 unit
⇒ side = 140 ÷ 4 = 35 unit
Area of a parallelogram = base × altitude = 35 × altitude = 42 unit
⇒ Altitude = 1.2 unit
