Answer:
The number of tree is 2
Step-by-step explanation:
the diagonal of the rectangular plot of land can be found using Pythagoras theorem (the diagonal is the hypotenuse)
Given
length of land x= 48m
width of land y= 20m
digonal z= ?

substituting the values of x and y into the equation we can solve for z

The diagonal is 52m
Hence since the interval = 22m the number if treee is

The number of trees must be whole numbers , the number of tree is 2
