Exploring Go Math Chapter 11 Concepts

What does the area of a figure represent?

• The length of the figure

• The space inside the figure

• The space outside the figure

• The height of the figure

How do you calculate the perimeter of a figure?

• By multiplying the length and width

• By adding the distance around the figure

• By adding the length and width

• By dividing the length by the width

If a figure on a grid has a perimeter of 14 units, how many units does a side measure if all sides are equal?

• 3.5 units

• 14 units

• 5 units

• 7 units

For a picture needing a frame, if each side measures 6 cm, what is the total length of the trim needed?

• 12 cm

• 18 cm

• 30 cm

• 24 cm

What is the formula to calculate the area of a rectangle?

• (Length + Width) x 2

• Length / Width

• Length x Width

• Length + Width

If a rectangle on paper has a length of 2 units and a width of 4 units, what is its area?

• 12 square units

• 8 square units

• 10 square units

• 6 square units

In the context of a fort plan, if one side measures 4 feet and the adjacent side measures 7 feet, what is the area?

• 56 square feet

• 28 square feet

• 14 square feet

• 11 square feet

Which equation correctly represents the area of the fort plan?

• 4 + 4 + 4 + 4 = 16

• 7 + 4 + 7 + 4 = 22

• 4 x 7 = 28

• 7 + 7 + 7 + 7 = 28

Why is the equation 7 + 7 + 7 + 7 = 28 not suitable for calculating the area of the fort?

• It is suitable for calculating the area

• It calculates the perimeter instead

• It overestimates the area

• It underestimates the area

What mistake is commonly made when calculating the area of irregular shapes?

• Multiplying length by width incorrectly

• Adding instead of multiplying

• Calculating the perimeter instead of the area

• Ignoring the shape's irregularities
