Answer:
258.42 m²
Explanation:
Area of the carpet = area of the rectangle + area of the 3 semi circles
Area of rectangle = length × breadth
= 18m × 12m
= 216m²
Area of circle = (ϴ/360)*πr²
π = 22/7 or 3.14
In a semi circle ϴ = 180°
Here the 18m comprises of 6 radii therefore radius of 1 semi circle =
18/6 = 3m
Area of 1 semi circle
= 180/360 × 22/7 × 3²m
= 14.14 m²
Total = 216 + ( 14.14 ×3 ) = 258.42 m²
