A room is 5.4 m long and 4.2 m wide. It takes 1575 square tiles to cover the floor.
Calculate the area of each tile and work out
its dimensions.

Area of the room = 5.4m × 4.2 m

Thus area = 22.6

Number of square tiles = 1575

Thus The area of each tile:

Now the dimensions of square tile will be:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
