Question 993629
A rectangular parcel of land is 20 m wide. The length of the diagonal between the opposite corners is 5 m more than the length of the parcel. What is the length of the parcel? 
---
Draw the picture of the rectangle.
width = 20 m
length = x meters
diagonal = x+5 meters
----
Solve for "x"::
(x+5)^2 = x^2 + 400
----
x^2+10x + 25 = x^2 + 400
10x = 375
x = 37.5 meters (length)
