Question

A farmer has a rectangular field that is 100 yards long by 20 yards wide. What is the total area of the field?

Answer 1

A farmer has a rectangular garden plot surrounded by 200 ft of fence. Find the length and width of the garden if its area is 2400 square feet.
.
Let x = width
and y = length
.
The because he has 200 ft of fencing, this must lest than or equal to the perimeter:
2(x+y) = 200
x+y = 100
Solving for x:
x+y = 100
x = 100-y

Answer 2

The area of the field is equal to the area of rectangular
a = l × w

Given:
l = 100 yards
w = 20 yards

Solution:
put the numbers to the formula
a = l × w
a = 100 × 20
a = 2,000
The area of the field is 2,000 square yards
