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
