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

No, the correct answer is 32cm.

Step-by-step 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 .

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

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

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
