Question

A rectangular field is 400 meters long and 350 M wide what is the area of the field in square kilometers do not round the answer and be sure to include the correct unit in the answer

Answer 1

The area of rectangular field is 0.14 square kilometer

Solution:

Given that rectangular field is 400 meters long and 350 meter wide

To find: area of the field in square kilometers

The area of rectangle can be found out by multiplying length and width of rectangle

The area of rectangle is given as:

$\text { Area of rectangle }=\text { length } \times \text { width }$

Given that length = 400 meter and width = 350 meter

Substituting the values in above formula we get,

$\text { Area of rectangle }=400 \times 350=140000$

Thus the area of rectangle is 140000 square meters

Converting the area of rectangle to square kilometers:

To convert meter to kilometer, divide the value by 1000

$1 \text { meter }=\frac{1}{1000} \text { kilometer }$

Therefore,

$\begin{array}{l}{1 \text { meter }^{2}=\frac{1}{1000 \times 1000} \text { kilometer }^{2}} \\\\ {1 m^{2}=\frac{1}{1000000} k m^{2}}\end{array}$

$140000 \mathrm{m}^{2}=\frac{140000}{1000000} \mathrm{km}^{2}=\frac{14}{100} \mathrm{km}^{2}=0.14 \mathrm{km}^{2}$

Thus the area of rectangular field is 0.14 square kilometer
