peter is trying to get his cat out of a tree in his backyard. The cat is 12feet above the ground, and Peter has to put the base

Vadim26 [7]

Answer:

15 feet

Step-by-step explanation:

Given that,

The cat is 12feet above the ground, and Peter has to put the base of his ladder 9 feet away from the tree because of mud.

If we consider a right-angled triangle, in which the height is 12 feet, base is 9 feet.

We need to find how long does the ladder need to be in order to reach the cat i.e. the hypotenuse of the triangle.

We can use the Pythagoras theorem to find it.

$H^2=h^2+b^2\\\\H^2=12^2+9^2\\\\H^2=144+81\\\\H=\sqrt{225} \\\\H=15\ \text{feet}$

So, the ladder must be at a distance of 15 feet in order to reach the cat.

Answer:

Step-by-step explanation:

You find the area of each triangle and that is (4*3)/2 which is equal to 6 but because all four sides are the same size you would multiply 6 by 4 so 6*4=24 you must also find the area of the bottom and that would be 3*3= 9 then you'd add them together 24+9=33 i hope that this helps!
