Answer 1

Answer:

The outer area of the table - 8649 sq cm

The area of the frame - 549 sq cm

Step-by-step explanation:

Area of square table = side ×side

= 90×90 sq cm

= 8100 sq cm

Side of outer area of the table = 90cm + 3cm

= 93 cm

The outer area of the table = side × side

= 93 × 93 sq cm

= 8649 sq cm

The area of the frame = 8649 sq cm - 8100 sq cm

= 549 sq cm .
