Step-by-step explanation:

Lanie's room is in the shape of a parallelogram.

Lanie has a rectangular rug that is 6 feet wide and 10 feet long.

Area of a rectangle = Length × Width

Area of the rectangular rug = 10 feet × 6 feet

= 60 square feet

We are told that:

The floor of her room is shown below and has an area of 108 square feet.

Alla [95]

Answer:

t > 1380

Step-by-step explanation:

Subtract 7200 from both sides

Simplify

10t > 13800

Divide both sides by 10

10t/10 > 13800/10
