Find the cost of carpeting a room 3.6m high at Rs 120 per square meter if it contains 240 mcube of air

Rs 8000

Step-by-step explanation:

Volume = Base area × Height

If we want to find the cost of carpeting a room, we need to find how much space there is to carpet, which would be the base area of the room.

240m³ = Base area × 3.6m

Base area = 240m³ ÷ 3.6m

Base area = 66m²

1m² --- Rs 120

66m² --- 66 × Rs 120 = Rs 8000

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
