Exploring Area of Composite Figures

What is the first step in finding the area of a composite figure?

• Multiply the lengths of all sides

• Divide the figure into simpler shapes

• Calculate the perimeter

• Guess the area based on the figure's complexity

How do you find the area of a triangle?

• Pi x Radius squared

• (Base x Height) / 2

• Length x Width

• Base + Height

What is the formula to find the area of a semicircle?

• (Pi x Radius squared) / 2

• Pi x Diameter squared

• Length x Width / 2

• (Base x Height) / 2

How do you calculate the area of a composite figure that includes a rectangle with a missing rectangular piece?

• Divide the larger rectangle's area by the smaller one

• Subtract the smaller rectangle's area from the larger one

• Add the areas of both rectangles

• Multiply the areas of both rectangles

What is the area of a rectangle calculated by?

• Pi x Radius squared

• Length + Width

• (Base + Height) / 2

• Base x Height

How do you find the base of a triangle when given partial measurements?

• Add all given lengths

• Subtract the known lengths from the total length

• Multiply the known lengths

• Divide the total length by the number of sides

What is the first step in handling a complex composite figure?

• Multiply all given dimensions

• Divide it into known shapes

• Calculate the perimeter first

• Estimate the total area

How do you determine the radius of a semicircle when given the diameter?

• Multiply the diameter by 2

• Divide the diameter by 2

• Add Pi to the diameter

• Subtract 2 from the diameter

What is the correct formula to calculate the area of a trapezoid?

• (Base1 + Base2) x Height

• Pi x Radius squared

• (Base1 + Base2) x Height / 2

• Base x Height

When calculating the area of a composite figure, what should you do after finding the areas of individual parts?

• Multiply them

• Add them together

• Divide one area by the other

• Subtract them from each other
