• It has 4 equal sides and 4 right angles

• It has 1 right angle and 4 equal sides

• It has 3 right angles and 4 equal sides

The polygon can be decomposed into two triangles to determine the area of the polygon.

Which decomposition of two triangles represents the area of the polygon?

• The area of triangle GHL plus the area of triangle HIJ

• The area of triangle GHK plus the area of triangle HIK

• The area of triangle GJK plus the area of triangle ILK

• The area of triangle GHK plus the area of triangle ILK
