I hope this helps!
But you should really do this yourself.
Answer:
(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
