Find the area of a rectangular field if its length is 3 km and width is 1 km less

Given:
length – 3 km
width -?, 1 km less (than the length, show with an arrow to the length)
To find:
S -? hectares
Solution:
First, find the width of the rectangular box
3 – 1 = 2 (km)
Now, since the field has the shape of a rectangle, we will find its area using the formula for finding the area of a rectangle
S = a * b
S = 3 * 2
S = 6 km2
S = 600 hectares
Answer: the area of a rectangular field is 600 hectares
