उत्तर
(1) The area of leaf 1
= 1 × (Number of complete squares) cm2
+ `1/2` (Number of half or more than half squares) cm2
= 1 × 3 cm2 +`1/2 `× 5 cm2
= 3 cm2 + 2.5 cm2
= 5.5 cm2
(2) The area of leaf 2
= 1 × (Number of complete squares) cm2 + `1/2`× (Number of half or more than half squares) cm2
= 1×3 cm2 + `1/2` × 5 cm2
= 3 cm2 + 2.5 cm2
= 5.5 cm2
(3) The area of leaf 3
= 1 × (Number of complete squares) cm2
+ `1/2 `× (Number of half or more than half squares) cm2
= 1 × 7 cm2 + `1/2`× 9 cm2
= 7 cm2 + 4.5 cm2
= 11.5 cm2
(4) The area of leaf 4
= 1 × (Number of complete squares) cm2
+ `1/2` × (Number of half or more than half squares) cm2
= 1× 6 cm2 +`1/2`× 8 cm2
= 6 cm2 + 4 cm2
= 10 cm2
(5) The area of leaf 5
= 1 × (Number of complete squares) cm2
+ `1/2`× (Number of complete squares) cm2
= 1 × 6 cm2 + `1/2` × 9 cm2
= 6 cm2 + 4.5 cm2
= 10.5 cm2
