Decomposing Shapes and Area Calculation

Ramon attempted to find the area of a polygon by dividing it into two shapes, but his method was incorrect. The video explains why his approach was ineffective and suggests a better method. By dividing the polygon into a triangle and a rectangle, the area can be calculated more easily. The correct method involves using known dimensions to find the areas of simpler shapes.

What shape did Ramon initially try to decompose?

• Hexagon

• Rectangle

• Pentagon

• Triangle

Why was Ramon's initial method incorrect?

• He forgot to measure the base.

• The shapes he created were difficult to calculate.

• He didn't consider the height of the shapes.

• He used the wrong formula.

What is the height of the triangle in the correct method?

• 10

• 3

• 14

• 5

What is the length of the base of the triangle in the correct method?

• 3

• 14

• 5

• 10

What are the dimensions of the rectangle in the correct method?

• 10 by 5

• 14 by 3

• 14 by 5

• 5 by 3

What should Ramon do next time to correctly find the area?

• Measure the perimeter first.

• Use a different polygon.

• Use a calculator.

• Draw a line to form a triangle and a rectangle.
