Question

On Diwali, your sister made a colorful rangoli and you noticed many mathematical shapes in it. As there was time to burst crackers, you started finding the area of orange colored part. You measured the bigger square's side as 30 cm by 30 cm and the smaller square's side to be 15 cm by 15 cm. What was the area of the orange colored part?

• A. 900 cm²
• B. 675 cm²
• C. 225 m²
• D. 60 m²

Answer 1

The correct option is B

675 cm²

To find the area of the orange shaded part, find the bigger square's area and subtract smaller square's area from that.
Bigger square's area = $30\times 30=900c{m}^2$
Smaller square's area = $15\times 15=225c{m}^2$
Area of orange shaded part = Bigger square's area - Smaller square's area = $(900-225)c{m}^2=675c{m}^2$
