Exploring Area of Composite Figures

What is the area of a square with a side length of 7 millimeters?

• 49 square millimeters

• 14 square millimeters

• 28 square millimeters

• 35 square millimeters

How do you calculate the area of a composite figure?

• Estimate visually without calculations

• Divide into simpler shapes and sum their areas

• Multiply the dimensions of the outer shape

• Use a specific formula for composite figures

If a triangle has a base of 7 yards and height of 14 yards, what is its area?

• 7 square yards

• 98 square yards

In the context of composite figures, what does 'part plus part equals whole' imply?

• Sum of areas of parts equals the area of the whole figure

• Each part is equal to the whole

• The whole is less than the sum of its parts

• The parts are unrelated to the whole

What is the result of subtracting the area of an inner shape from the area of an outer shape?

• Volume of the shape

• Area of the remaining part

• Total area of the composite figure

• Perimeter of the outer shape

What technique is used to find the area of a composite figure with a missing middle piece?

• Divide the figure into equal parts and find one area

• Multiply the dimensions of the outermost figure

• Add the areas of all visible pieces

• Subtract the area of the missing piece from the total

How do you find the radius of a circle if the circumference is given as 57.148 and pi is approximated as 3.14?

• None of the above

• Subtract pi from the circumference
