Question

Is this correct? Ive done this a million times and they always come out the same, but I still get it wrong.

Answer 1

No, the correct answer is 32cm.

Explanation:

First of all, lets cut the shape into two. A rectangle and a triangle. This will help us find the slanted side of the shape.

We will use the pythagorean theorem to find the length of the slanted line.

The pythagorean theorem is
`a^(2) +b^(2) =c^(2)`.

Input the given information of the triangle lengths that we know; that is the length= 6 and the base=3.

`c= \sqrt{a^(2)+b^(2) } =\sqrt{6^(2)+\ 3^(2) } = 6.7082`

Now, we round.

6.7082≈ 6.7

We have found the length of the slanted line of the shape.

Now, let's add all the lengths together.

8+6+6.7+11= 31.7

Now, lets round.

31.7 ≈ 32cm

Hope this helps!
