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.
Annika designs a hole for a miniature golf course. What is the area of Annika’s design in square feet?(1 point)
square feet
The area of Annika's design can be calculated by finding the area of each individual shape (rectangle, triangle, square) and then adding them together.
Rectangle:
Length = 12 feet
Width = 4 feet
Area = Length x Width = 12 feet x 4 feet = 48 square feet
Triangle:
Base = 4 feet
Height = 4 feet
Area = 1/2 x Base x Height = 1/2 x 4 feet x 4 feet = 8 square feet
Square:
Side length = 4 feet
Area = Side length^2 = 4 feet^2 = 16 square feet
Total Area = Rectangle Area + Triangle Area + Square Area
Total Area = 48 square feet + 8 square feet + 16 square feet
Total Area = 72 square feet
Therefore, the area of Annika's design is 72 square feet.
