The area of the composite shape in the diagram given is: 100 square inches.
<h3>How to Find the Area of a Composite Figure?</h3>
Area of a composite figure = sum of the areas of the shapes that make up the figure.
Area of the composite shape = 2(area of triangle) = 2(1/2bh)
Area of the composite shape = 2(1/2×10×10)
Area of the composite shape = 100 square inches.

L+l+L+l=120
L+l=60
