Question

The side of the bigger square is 30 cm and the side of the smaller square is 15 cm. What is the area of the orange colored part?

• A. $60m^2$
• B. $225m^2$
• C. $675c{m}^2$
• D. $900c{m}^2$

Answer 1

The correct option is C $675c{m}^2$

To find the area of the orange shaded part, first we have to 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 = $(900-225)c{m}^2=675c{m}^2$
