Answer 2

Answer:

1) 63cm²

2) 268cm²

Step-by-step explanation:

1) Middle Rectangle = 4 × 3 = 12

Little 'arms' = ( 1×1 ) × 2 = 2cm²

12+2 = 14cm² removed in total

Original size: 11 × (2+1+2+2) (which is 7) = 77cm²

77cm² - 14cm² = 63cm² left.

2) Left extruding part = 4 × 2 = 8cm²

Middle part = 4 × 6 = 24cm²

Right extruding part = 2 × 4 = 8cm²

In total 8 + 24 + 8 = 40cm² removed

Original area = 22 × ( 4+2+2+2+4 ) (which is 14) = 308cm²

308cm²- 40cm² = 268cm² left

Hope this helps!
