Question

4) The diagonals of a rhombus are 30cm and 16cm.Find its perimeter and area​

Answer 1

Rhombus Side = SQUARE ROOT [(Long Diag / 2)^2 + (Short Diag / 2)^2]

Rhombus Side = SQUARE ROOT [(30 / 2)^2 + (16 / 2)^2]

Rhombus Side = SQUARE ROOT (15^2 + 2 + 8^2)

Rhombus Side = SQUARE ROOT (225 + 64)

Rhombus Side = SQUARE ROOT (289)

Rhombus Side = 17 cm

Rhombus perimeter = 4 * side = 68 centimeters

(See attached formula)
