The length of the rectangular plot of land is 42 m. The width of the plot is half its length. Calculate the area of the site?

To solve this problem, as well as similar ones, we need to learn or remember some mathematical rules. In our case, we need to know the formula for the area of a rectangle, as well as be able to perform division and multiplication.

Formula for the area of a rectangle: S = a * b.

First, we need to know the width of the rectangle.

42: 2 = 21 (m)

Now we can find the area, for this we substitute the obtained values for the length and width in the formula. We get the following expression:

S = 42 * 21 = 882 (m2)

Answer: 882 m².
