Length times width = area, 10 X 15 = 150 Square feet.
Area of room = width * length = (2x-1)*(7x+3) = 14x2 + 6x - 7x - 3 = 14x2 - x - 3 sq feet

Area is length times width. So a 12 by 7 room has an area of 84 feet2.
To find the area of the floor, you need to multiply the length by the width of the room. Given that the room is 20 feet long and 12 feet wide, you can calculate the area as follows: Area of the floor = Length × Width = 20 feet × 12 feet = 240 square feet Therefore, the area of the floor is 240 square feet.

This room has an area of 11.71 (11.705783) square meters.
Area is length times width. The floor is 100 square feet.
You have to multiply the two dimensions to get the area. In this case the answer will be 117 square feet.
Perimeter = 38 feet Area = 90 square feet
You would find the area by multiplying the width by the length, so the area would be 216 square feet.
Length times width = area, 10 X 15 = 150 Square feet.
Area = length x height If you have a room three feet long and four feet wide, the area is 12 feet squared.
