what is the area of the quadrilateral? the base is 10 cm, the height is 6 cm, and the width is 6 cm.

To find the area of the quadrilateral, we need to first calculate the area of the rectangle and then subtract the area of the triangle on top.

Area of the rectangle = base x width
Area of the rectangle = 10 cm x 6 cm
Area of the rectangle = 60 square cm

Area of the triangle = (1/2) x base x height
Area of the triangle = (1/2) x 10 cm x 6 cm
Area of the triangle = 30 square cm

Area of the quadrilateral = Area of the rectangle - Area of the triangle
Area of the quadrilateral = 60 square cm - 30 square cm
Area of the quadrilateral = 30 square cm

Therefore, the area of the quadrilateral is 30 square cm.
