Question

What is the area of the composite figure shown?

Answer 1

think of it as the area of a square minus the area of the triangle

Answer 2

I think there is some information missing, either you need the length, or you need to know one of the angles. It 'seems' like the length is 50 too, but it could be anything.

Answer 3

its a square, the double dash on the lines means they're the same length

Answer 4

ah.. I didnt know that. Ok, then all the information is there :)
