Question

find the area of the polygon. do not forget about the proper unit notation. (hint: area of a triangle = 0.5 b h)
63.)
image of a square with side length 11 ft
=
64.)
image of a square with side length 3 ft
=

Explanation:

Problem 63:

Step1: Identify the shape and formula

The polygon is a square (or rectangle with length = width) with side length \( s = 11\) ft. The area of a square is given by \( A = s\times s\) (or \( A = l\times w\) where \( l = w\)).

Step2: Calculate the area

Substitute \( s = 11\) ft into the formula: \( A = 11\times11\)
\( A = 121\) square feet.

Step1: Identify the shape and formula

The polygon is a square (or rectangle with length = width) with side length \( s = 3\) ft. The area of a square is given by \( A = s\times s\) (or \( A = l\times w\) where \( l = w\)).

Step2: Calculate the area

Substitute \( s = 3\) ft into the formula: \( A = 3\times3\)
\( A = 9\) square feet.

Answer:

\( 121\) square feet (or \( 121\space ft^2\))
