The area of a rectangular floor is 135meter square where one side is 1.5 meter calculate the dimension of the floor

1.5 m by 90 m

Step-by-step explanation:

Recall that the formula for the area of a rectangle is A = L * W.

Here, the area is given:  A = 135 m^2, and this area is the product of the length and width of the rectangle:  135 m^2 = (1.5 m)(W), where W is the side of unknown length.

Solving for W:  W = (135 m^2) / (1.5 m) = 90 m

Thus, the dimensions of the floor are 90 m by 1.5 m.

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.
