Solution
Given dimensions of rectangular lawn = 10 m × 4 m and width of flower bed = 50 cm
Length of remaining portion,
EF = AB – (50 × 2 cm)
= 10 m – 100 cm ...`[∵ 1 cm = 1/100 m]`
= 10 m – 1 m
= 9 m
Breadth of remaining portion,
EH = AD – 50 cm
= 4 m – 0.5 m
= 3.5 m
∴ Required area = Area of portion EFGH
= EF × EH
= 9 × 3.5
= 31.5 m2
