Answer 1

Answer:

Area of veranda=106.2 m^2

cost =23,364

Explanation:

area of big rectangle= (6.5+6)×(5.2+6)=140 m^2

area of small rectangle=6.5×5.2=33.8 m^2

area of veranda= area of big rectangle-area of small rectangle

=140-33.8

=106.2 m^2

cost of cementing the floor of the veranda = 220×106.2=23,364
