Question

How can you decompose the composite figure to determine its area

1 as two triangles, two rectangles, and two semicircles
2 as a trapezoid, a rectangle, and two semicircles
3 as a regular hexagon, a rectangle, and two squares
4 as a trapezoid, a rectangle, and two squares

Answer 1

D

Explanation:

Answer 2

4 as a trapezoid, a rectangle, and two squares

Explanation:

The diagram below is a composite figure .To determine it area the composite figure can be decomposed into various shapes.

The shapes it can be decomposed are a trapezoid , a rectangle and 2 squares.

The top side of the composite figure forms a trapezoid . A trapezoid is a quadrilateral with one pair of parallel sides. It is also known as trapezium.

The shape below the trapezoid can be cut into a rectangle .A rectangle is a quadrilateral with opposite sides equal in length and are also parallel.

The two shapes formed below the rectangle are squares. Squares are quadrilaterals with all sides equal in length and opposite sides are parallel.
