Question

The total distance around Regina rectangular shaped bedroom is 300 feet, the length of the room is 80 feet. What is the area of Regina bedroom

Answer 1

Answer:

5600 square feets

Step-by-step explanation:

Let $l, b$ denote length and breadth of the rectangular shaped bedroom.

The total distance around Regina rectangular shaped bedroom is 300 feet.

$2(l+b)=300\\l+b=150$

The length of the room is 80 feet.

Put $l=80$

$80+b=150$

$b=150-80=70$ feets

Area of the rectangular shaped bedroom $=lb=80(70)=5600$ square feets.
