find the area of each square.
1)
2)
area =
area =
find the area of each rectangle.
1)
2)
area =
area =
find the area of each triangle.

Explanation:

Step1: Recall area formula for square

The area formula for a square is $A = s^2$, where $s$ is the side - length of the square.

Step2: Calculate area of first square

For the first square with side - length $s = 8.8$ yards, $A_1=(8.8)^2=77.44$ square yards.

Step3: Calculate area of second square

For the second square with side - length $s = 10.6$ inches, $A_2=(10.6)^2 = 112.36$ square inches.

Step4: Recall area formula for rectangle

The area formula for a rectangle is $A=l\times w$, where $l$ is the length and $w$ is the width.

Step5: Calculate area of first rectangle

For the first rectangle with length $l = 13.6$ yards and width $w = 2.21$ yards, $A_3=13.6\times2.21 = 30.056$ square yards.

Step6: Calculate area of second rectangle

For the second rectangle with length $l = 14.7$ feet and width $w = 8.6$ feet, $A_4=14.7\times8.6=126.42$ square feet.

Answer:

1. Square 1 area: 77.44 square yards
2. Square 2 area: 112.36 square inches
3. Rectangle 1 area: 30.056 square yards
4. Rectangle 2 area: 126.42 square feet
