Question

what is the total amount of fencing needed to enclose the plot of land shown below? 140 ft 240 ft

Explanation:

Step1: Encontrar la hipotenusa

$$\begin{align*} c^{2}&=a^{2}+b^{2}\\ c^{2}&=60^{2}+80^{2}\\ c^{2}&=3600 + 6400\\ c^{2}&=10000\\ c&=\sqrt{10000}\\ c& = 100 \end{align*}$$

Step2: Calcular el perímetro

$$\begin{align*} P&=a + b+ c\\ P&=60+80 + 100\\ P&=240 \end{align*}$$

Answer:

240 ft
