Question

the big room is 14.5 M long and 8.5 M wide it has a verandah 2.5 M wide all around find the area of the verandah and the cost of cement in the verandah at rupees 10 per square metre

Answer 1

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

Area of the room is given by 4 * 5.5 = 22m2

Area of the verandah with room is (5.5 + 1.25 + 1.25) * (4 + 1.25 + 1.25) = 8 * 6.5 = 52

Area of only verandah = 52 - 22 = 30m2

Cost of cementing the floor of the verandah = 15 Rs/m2

Total cost of cementing 30m2 verandah = 30 * 15 = 450 Rs
