Answer» Diameter of the Circular Garden = d d = 42 m Radius ( r )= OB = d/2 = 42/2 = 21 m width of the around the Garden (w)=3.5m Radius of the larger circle ( R ) = OA = r + w R = 21 + 3.5 = 24.5 m Area of the Road ( A ) = π( R+r )( R-r ) A = ( 22/7 ) ( 24.5 + 21 )( 24.5 - 21 ) A = ( 22/7 ) × 45.5 × 3.5 A = 22 × 45.5 × 0.5 A = 500.5 m² Therefore , Area of the Road = A = 500.5 m² please like the solution 👍 ✔️👍

Answer»

Diameter of the Circular Garden = d

d = 42 m

Radius ( r )= OB = d/2 = 42/2 = 21 m

width of the around the Garden (w)=3.5m

Radius of the larger circle ( R )

= OA

= r + w

R = 21 + 3.5 = 24.5 m

Area of the Road ( A ) = π( R+r )( R-r )

A = ( 22/7 ) ( 24.5 + 21 )( 24.5 - 21 )

A = ( 22/7 ) × 45.5 × 3.5

A = 22 × 45.5 × 0.5

A = 500.5 m²

Therefore ,

Area of the Road = A = 500.5 m²
