Answer:
1) 63cm²
2) 268cm²
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!
