1 point A rectangular ballroom is being carpeted. The room measures 12 feet by 11 feet. If the carpet costs $3.60 per square foot, then what is the cost of
the carpet?

first lets find the area of the floor.

A=l*w     where l=length and w=width

Plug in the data

A=14*12

A=168ft²

If 1 square foot of carpet is 2.90$, then 168 square feet are...

 1 sqft         168sqft

=

 2.90$             x$

Cross multiply

1x=487.20

divide both sides by 1

x=487.20 dollars

Answer= $487.20

Step-by-step explanation:

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
