Question

rekha draws a rhombus with diagonals measuring 40cm and 15cm. She needs to
cover it completely with a coloured sheet. What will be the area of the coloured
sheet required to cover the rhombus

Answer 1

The sheet required to cover the rhombus is: 300 sq. cm.

Area of a Rhombus

• Area of a rhombus can be calculated using the following formula, A = (ab)/2.
• Where, a and b are diagonal lengths of the rhombus.

Thus:

a = 40 cm

b = 15 cm

Sheet required to cover the rhombus = area of the rhombus.

Area = (40 × 15)/2

Area = 300 sq. cm.

Therefore, the sheet required to cover the rhombus is: 300 sq. cm.
