Area of Cementing =

8x.8x2+6x.8x2

12.8+9.6=22.4m2

cost@Rs 5

22.4x5 = Rs. 112 Ans

Answer 2

The cost of cementing a verandah would be Rs. 124.8.

Step-by-step explanation:

Since we have given that

Length of room = 8 m

Breadth of room = 6 m

Width of verandah = 80 cm = 0.8 m

So, Length of verandah = 8 + 0.8 +0.8 = 9.6 m

Breadth of verandah = 6 + 0.8+0.8 = 7.6 m

So, Area of outer part is given by

$Length\times breadth\\\\=9.6\times 7.6\\\\=72.96\ m^2$

Area of room is given by

$Length \times breadth\\\\=8\times 6\\\\=48\ m^2$

So, the area of verandah is given by

$72.96-48=24.96\ m^2$

Cost of per sq. m. = Rs. 5

So, Cost of cementing a verandah would be

$24.96\times 5=124.8$

Hence, the cost of cementing a verandah would be Rs. 124.8.
