I have a complex figure like a U shape.
I understand the formula for this is l x w = a
Can you show me the steps?
31m is parael to 31m this would be the height (sides of the U)?? or is this the width?
Length 69m
Width is on the right top of U 23m.
Inside the middle of the U23m
Inside the middle side 12m
So confused can anyone help?

Reiny,
I think I got your figure.
I assume that the height of the inside of the U is 12 m
continue those height to the base, you now have 3 rectangles, the two outside ones are equal and are
31 by 23
The smaller one at the base is 23 by (3112)
or 23 by 19
total area = 2(31)(23) + (23(19)
= 1426 + 437 = 1863

Max,
yes hieght is 12m
Yes 3 rectangles.
yes two outside ones equal 31 by 23
Yes smaller one at the base is 23m
Yes all right. your awesome! This was a tough one for me. But you helped me see where I was confused.
Thank you so much.
