How do I calculate square feet of a room that is L shaped?

Answer 1

Divide the L-shape into two rectangles, and compute the area of each rectangle separately. Then add the two areas.

Answer 2

The room is made up of 2 rectangles.

Take the width of one of the rectangles and subtract it from the length of the other rectangle.

Now you have

1st Rectangle
L1 and W1

1st Rectangle Area = L1 * W1

2nd Rectangle
W2 and L2 - W1

2nd Rectangle Area = (L2 - W1)W2

To get the Area, just add the 2 rectangles together

R1 + R2 = Total Area

(L1W1) + (L2 - W1)W2 = TA

For example, lets say your room measures
Lengths = 9ft and 12ft
Widths = 4ft and 3 ft

Respectivly

L1 = 9
W1 = 3
L2 = 12
W2 = 4

(L1W1) + (L2 - W1)W2 = TA
(9 * 3) + 4(12 - 3) = TA
27 + 4(9) = TA
27 + 36 = TA
TA = 63 ft^2

Answer 3

Divide the room into 2 sections of rectangle. Compute for each area. Then add them to get the whole room area.

Answer 4

Separate the L into two pieces. Measure each section, using the Area = Length x Width principal. Then, add the two sums together.

Answer 5

The product of the longer x and y values MINUS the product of the shorter x and y values.

Or said another way, a big rectangle minus a smaller rectangle.

Answer 6

the same way you would do any square or rectangle just measure one and then the other and add!

Answer 7

break it up in to two rectangles and add the area of those rectangel together
