Solution
We have, length and breadth of inner rectangle is 60 cm and 38 cm, respectively.
∴ Area of inner rectangle = 60 × 38 = 2280 cm2 ...[∵ Area of rectangle = Length × Breadth]
∴ Breadth of outer rectangle = 38 + 6 + 6 = 50 cm
Length of outer rectangle = 60 + 6 + 6 = 72 cm ...[∵ Width of frame = 6 cm, given]
∴ Area of outer rectangle = 50 × 72 = 3600 cm2
Now, area of wooden frame = 3600 – 2280 = 1320 cm2
