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

5600 square feets

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.
