Question

for a rectangular piece of land on a cattle station where: b = 4.9 km, h = 1.65 km, the area is:

Explanation:

Step1: Recall rectangle area formula

The area \( A \) of a rectangle is given by the formula \( A = b \times h \), where \( b \) is the base (length) and \( h \) is the height (width).

Step2: Substitute given values

We are given \( b = 4.9 \) km and \( h = 1.65 \) km. Substitute these values into the formula:
\( A = 4.9 \times 1.65 \)

Step3: Calculate the product

First, multiply \( 4.9 \) and \( 1.65 \):
\( 4.9 \times 1.65 = (5 - 0.1) \times 1.65 = 5 \times 1.65 - 0.1 \times 1.65 = 8.25 - 0.165 = 8.085 \)

Answer:

The area of the rectangular piece of land is \( 8.085 \) square kilometers.
