Molly wants to put a fence around an area. The fence will follow the diagram of the triangle shown below.

About how much fencing does Molly need?

Molly would need 43 feet of fencing to fence the area.

Step-by-step explanation:

We can see that the area is in the form of a right-angled triangle. Since only two sides of the triangle is given, we could utilise Pythagoras theorem to our advantage to find out the third side.

In Δ ABC

AB² (base) + AC² (perpendicular) = BC² (hypotenuse)

Substituting the values of AB as 10 feet and BC as 18 feet

AC²= BC²- AB ²

∴AC²= 224  

∴AC= 14.96 cm

Amount of fence required by molly would equal perimter of the area.

⇒The perimeter of the area would equal AB+BC+AC

⇒Summing up the values of AB, AC and BC

Perimeter= 10+14.96+18= 42.96 feet which is about 43 feet

Hence, Molly would require 43 feet of fencing.

correct answer:

i^31 = -i

can you rephrase the question ? it is unclear : -)
