Question

here's a scale drawing of a garden if 2 cm on the scale drawing equals 3 ft of fencing how many total feet of fencing are needed to enclose this Garden

Answer 1

Determine the length of fencing required for the garden in cm.

$\begin{gathered} L=7+1+1+4+1+1+7+1+1+4+1+1 \\ =30 \end{gathered}$

If 2 cm is equivalent to 3 feet. Then 30 cm is equal to,

$\begin{gathered} 30\operatorname{cm}\times\frac{3\text{ ft}}{2\text{ cm}}=15\cdot3\text{ ft} \\ =45\text{ ft} \end{gathered}$

So answer is 45 feet.
