Hector designs the piece of jewelry shown below. All lengths are marked in centimeters. What is the total area of the piece of jewelry? all the sides are 9cm, 2cm, 3cm, 2cm (1 point)
To find the total area of the piece of jewelry, we need to calculate the area of each individual shape and then add them together.
First, let's calculate the area of the rectangle with sides 9cm and 2cm:
Area = length x width
Area = 9cm x 2cm = 18 cm²
Next, let's calculate the area of the rectangle with sides 9cm and 3cm:
Area = length x width
Area = 9cm x 3cm = 27 cm²
Now, let's calculate the area of the square with sides 2cm:
Area = side x side
Area = 2cm x 2cm = 4 cm²
Finally, let's calculate the area of the triangle with base 2cm and height 3cm:
Area = 1/2 x base x height
Area = 1/2 x 2cm x 3cm = 3 cm²
Now, let's add up all the individual areas to get the total area of the piece of jewelry:
Total area = 18 cm² + 27 cm² + 4 cm² + 3 cm²
Total area = 52 cm²
Therefore, the total area of the piece of jewelry is 52 cm².
that is not a answer
I apologize for the error in my previous response. Let's try calculating the total area again.
We have four shapes forming the jewelry: two rectangles, one square, and one triangle.
Let's calculate the area of each shape:
Rectangle 1: 9cm x 2cm = 18 cm²
Rectangle 2: 9cm x 3cm = 27 cm²
Square: 2cm x 2cm = 4 cm²
Triangle: (1/2) x 2cm x 3cm = 3 cm²
Now, let's add up the areas of all the shapes to get the total area of the piece of jewelry:
Total area = 18 cm² + 27 cm² + 4 cm² + 3 cm²
Total area = 52 cm²
Therefore, the correct total area of the piece of jewelry is 52 cm². Thank you for your patience.
