Question

find the area.
3 in
area of □ = ? in²
10 in
area of □ = in²
15 in
remember: a□ = s²
10 in
area of figure = in²

Explanation:

Step1: Calculate the area of the square

The formula for the area of a square is \(A = s^{2}\), where \(s = 10\) in.
\(A_{square}=10\times10 = 100\) \(in^{2}\)

Step2: Calculate the area of the rectangle

The width of the rectangle is \(3\) in and the length is \(15\) in. The formula for the area of a rectangle is \(A=l\times w\).
\(A_{rectangle}=3\times15=45\) \(in^{2}\)

Step3: Calculate the total area of the figure

The total area of the figure is the sum of the area of the square and the area of the rectangle.
\(A_{total}=A_{square}+A_{rectangle}=100 + 45=145\) \(in^{2}\)

Answer:

Area of \(\square\) (square) \(= 100\) \(in^{2}\)
Area of \(\square\) (rectangle) \(= 45\) \(in^{2}\)
Area of Figure \(= 145\) \(in^{2}\)
