Question

question 10 (1 point)
find the area.
15 ft
7 ft
19 ft
area = square feet
blank 1:

Explanation:

Step1: Calculate the area of the larger rectangle

The formula for the area of a rectangle is \(A = l\times w\). For the larger rectangle with length \(15\) ft and width \(7\) ft, the area \(A_1=15\times7 = 105\) square feet.

Step2: Calculate the length of the smaller rectangle

The length of the smaller rectangle is \(19 - 15=4\) ft. The width of the smaller rectangle is \(4\) ft.

Step3: Calculate the area of the smaller rectangle

Using the area formula \(A = l\times w\) again, for the smaller rectangle with \(l = 4\) ft and \(w = 4\) ft, \(A_2=4\times4=16\) square feet.

Step4: Calculate the total area

The total area \(A=A_1 + A_2\). So \(A=105+16\).

Answer:

\(121\)
