Expert Solution

Answer to Problem 43E

The length of parcel is 120 ft.

Explanation of Solution

Given:

The width of parcel is 50 ft.

The length of diagonal is 10 ft more than the length of parcel.

Calculation:

Let the length of parcel be x.

Tabulate the given information into the language of algebra.

In words In Algebra
length of parcel x
Diagonal of parcel x+10

Model the equation for the above information.

(Length)2+(Width)2=(Diagonal)2x2+(50)2=(x+10)2

Simplify the above equation for x,

x2+2500=x2+100+20x20x=2400x=120

Thus, the length of parcel is 120 ft.
