Annika designs a hole for a miniature golf course. What is the area of Annika’s design in square feet?(1 point)
the answer is 72. can you explain why?
Without specific dimensions or shape of the design provided, it is not possible to calculate the area of Annika's design in square feet. We need more information regarding the dimensions or shape of the design in order to calculate the area.
these are the dimensions:
A composite shape is made up of a rectangle, triangle, and square. A horizontally aligned rectangle has a length of 12 feet and width of 4 feet. A right triangle adjoins the rectangle on the right side, with the vertical side common to the rectangle. A square with a side of 4 feet adjoins the right triangle along the bottom. Right angle marks are located in the four corners of the rectangle and the square, and also in the triangle where the base and vertical side meet.
thank you for allowing me to help
You're welcome! Feel free to ask if you have any more questions or need assistance. I'm here to help.
My apologies for the miscalculation. Let's reevaluate the calculations:
Area of the rectangle = length x width
Area of the rectangle = 12 feet x 4 feet = 48 square feet
Area of the triangle = 1/2 x base x height
Base of the triangle is the width of the rectangle = 4 feet
Height of the triangle can be calculated using the Pythagorean theorem:
c^2 = a^2 + b^2
c^2 = (12 feet)^2 + (4 feet)^2
c^2 = 144 square feet + 16 square feet
c^2 = 160 square feet
c = √160 feet = 12.65 feet
Height of the triangle = 12.65 feet
Area of the triangle = 1/2 x 4 feet x 12.65 feet = 25.3 square feet
Area of the square = side x side
Area of the square = 4 feet x 4 feet = 16 square feet
Total area of the composite shape = Area of rectangle + Area of triangle + Area of square
Total area = 48 square feet + 25.3 square feet + 16 square feet
Total area = 72.3 square feet
Therefore, the corrected area of Annika's design is approximately 72.3 square feet. Thank you for bringing this to my attention.
To calculate the area of the composite shape made up of a rectangle, triangle, and square, we will first find the area of each individual component and then add them up.
Area of the rectangle = length x width
Area of the rectangle = 12 feet x 4 feet = 48 square feet
Area of the triangle = 1/2 x base x height
The base of the triangle is the width of the rectangle = 4 feet
The height can be found using the Pythagorean theorem:
c^2 = a^2 + b^2
c^2 = (4 feet)^2 + (12 feet)^2
c^2 = 16 feet^2 + 144 feet^2
c^2 = 160 feet^2
c = √160 feet ≈ 12.65 feet
Height of the triangle = 12.65 feet
Area of the triangle = 1/2 x 4 feet x 12.65 feet ≈ 25.3 square feet
Area of the square = side x side
Area of the square = 4 feet x 4 feet = 16 square feet
Total area of the composite shape = Area of rectangle + Area of triangle + Area of square
Total area = 48 square feet + 25.3 square feet + 16 square feet
Total area ≈ 89.3 square feet
Therefore, the area of Annika's design is approximately 89.3 square feet.
