Answer:

Step-by-step explanation:

AREA OF ROOM=LENGTH*BREADTH

=14.5*8.5

123.25m²

length of room including verandah

=14.5+2.5+2.5=19.5

BREADTH of room including verandah=

=8.5+2.5+2.5=13.5

Area of room including verandah=19.5*13.5

=263.25m²

required cost of cementing the verandah=263.25*10=2632.5 rupees

Answer 2

Step-by-step explanation:

length of room = 14.5m

breadth of room=8.5m

area of room = 14.5×8.5

=123.25m²

length of room without veranda = 14.5-2.5

= 12 cm

breadth of room without veranda= 8.5-2.5

=6 cm

area of room without veranda= 12×6

= 72 cm

area of veranda = 123.25-72

= 51.25
