A rectangular piece of paper has a width that is three inches less than it’s length. It is cut in half along a diagonal to create two congruent right triangles with areas of 44 square inches.

(Measure ) L+W :  11 and 8 inches.

These L + W measures are of each triangle and when either halved as proven below will show (A): 44inch^2

Step-by-step explanation:

Two congruent triangles of 44 sq inch = base 8  height  11  

or base 11 height 8

Finding that both numbers find the same area.

Note for future areas either measure for triangle base + height

8 x 11 or 11 x 8 = 88  when halved its the same answer.  

where 7 x 10 = 35

13 x 10 = 65

and so on;

No other number multiplies its length and height to show 44
