Find the area of the orange colored part. The measure of the side of outer and inner square is 30 cm and 15 cm, respectively.
To find the area of the orange region,
Area of outer square =30×30=900 cm2
Area of inner square =15×15=225 cm2
Area of orange region
= Area of outer square - Area of inner square =(900−225) cm2=675 cm2
