Question

The area of a rectangular field is 80 square meters. If its length is 20 m, how far would you have travelled if you walked the whole way around the field?

Answer 1

Answer: We can start by finding the width of the rectangular field using the formula for area of a rectangle:

Area = length x width

80 = 20 x width

width = 4 meters

Now we can use the formula for perimeter of a rectangle:

Perimeter = 2 x length + 2 x width

Perimeter = 2 x 20 + 2 x 4

Perimeter = 40 + 8

Perimeter = 48 meters

So, you would have traveled 48 meters if you walked the whole way around the field.
