Applying the distance formula, the perimeter of the plot of land, rounded to the nearest tenth, is: 482.8 ft.

What is the Distance Formula?

Distance formula is given as: $$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$$.

Name the coordinates of the plot of and as follows:

A (0, 120)

B (140, 100)

C (140, 20)

D (0, 0)

Perimeter of the plot of land = AB + BC + CD + AD

AD = |120 - 0| = 120 ft

BC = |100 - 20| = 80 ft

Use the distance formula to find AB and CD:

AB = √[(140−0)² + (100−120)²]

AB = √20000

AB = 141.4 ft

CD = √[(140−0)² + (20−0)²]

CD= √20000

CD = 141.4 ft

Perimeter of the plot of land = 141.4 + 141.4 + 120 + 80 = 482.8 ft.
