Question

What is the perimeter of the following figure?

Perimeter = _____ cm

Answer 1

Perimeter=38cm

Explanation:

We have sides 9, 10, 5, and 4 cm

But there are 2 sides missing.

We see that 1 missing side is part of a square, in which all sides are equal, so the top missing side is 4cm.

We calculate the other missing side by taking the bottom side and subtracting 4cm from that.

This way we get the second missing side=6cm

Now we can add all of them

9+10+5+4+4+6=38cm
