Understanding Area and Perimeter of Irregular Shapes

What is the first step in finding the perimeter of an irregular shape?

• Divide the shape into smaller shapes

• Add up all the sides

• Cross out irrelevant measurements

• Multiply the length by the width

What is the perimeter of the irregular shape mentioned?

• 24 centimeters

• 30 centimeters

• 32 centimeters

• 26 centimeters

How do you calculate the area of an irregular shape?

• By dividing the perimeter by the number of sides

• By adding the area of smaller shapes

• By subtracting the smallest side from the largest

• By multiplying the perimeter by two

Why are some measurements crossed out when calculating the area?

• Because they are incorrect

• Because they are too large

• Because they do not apply to the smaller shapes

• Because they are redundant

How many rectangles were used to calculate the area of the irregular shape?

• Three

• Two

• Four

• One

What is the correct way to find the area of an irregular shape?

• By measuring its height only

• By dividing it into smaller, calculable shapes

• By using the Pythagorean theorem

• By dividing it into triangles

What measurements are necessary to calculate the area of a rectangle?

• Length and width

• Perimeter and length

• Length and height

• 24 square centimeters

What is the area of the top rectangle created from the irregular shape?

• 24 square centimeters

• 18 square centimeters

• 12 square centimeters

• 36 square centimeters

What should you do if an irregular shape cannot be divided into two rectangles?

• Use a different method

• Only calculate the perimeter

• Divide it into more rectangles

• Guess the area
