Finding area
I need to know how they got area as 90 in sq.
Square with triangle on the side. So 1 base is 13 in height 10. Top base is 8 in right side where triangle is top shows 6 in then base of triangle 6.4 in
square? with base not the same as the height?
top base??
Why not describe the diagram, where each point of interest is labeled. Square is ABCD, triangle is EFG, etc.
Then give the lengths of labeled sides.
Surely you know how to find the area of squares and triangles ...
