A comfort room which is 2m by 2m has to be tiled with 30 cm by 30 cm tiles. Is 50 pieces tiles enough to cover the comfort room. Illustrate your answer

yes

number of tiles needed = (200 x 200) / (30 x 30) = 44.4

Step-by-step explanation:

number of tiles needed = Area of comfort room / area of tiles

Area of a square = length²

convert area of comfort room to cm

100 cm = 1 meter

2 x 100 = 200

number of tiles needed = (200 x 200) / (30 x 30) = 44.4

50 tiles are more than enough to tile the room

step-by-step explanation:

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
