Question

what is the area of this figure? 7 km 13 km 8 km 5 km 18 km 4 km square kilometers

Explanation:

Step1: Calculate the area of the first rectangle

The first rectangle has dimensions \( (13 + 5)\text{ km}\) (height) and \(7\text{ km}\) (width).
The area formula for a rectangle is \(A = l\times w\).
So, \(A_1=(13 + 5)\times7=18\times7 = 126\text{ km}^2\)

Step2: Calculate the area of the second rectangle

The second rectangle has dimensions \(18\text{ km}\) (length) and \(4\text{ km}\) (width).
Using the area formula \(A = l\times w\), we get \(A_2=18\times4=72\text{ km}^2\)

Step3: Sum the areas of the two rectangles

The total area \(A = A_1+A_2\)
\(A=126 + 72\)

Answer:

\(198\)
