Question

Can someone please help me

Answer 1

We have all the information we need to complete this question, except the distance of the hypotenuse of the triangles. We find the length of the hypotenuses with the pythagorean theorem. The pythagorean theorem is:


`a^(2)+ b^(2) = c^(2)` where c squared is the hypotenuse.

Now, we plug in the numbers.


`15^(2) + 20^(2) = c^(2)`

Now, we solve for c.


`225+400= c^(2) --\ \textgreater \ c=√(625) =25`

So, the hypotenuse of the triangles is 25. Now, we can add up all the sides to find the perimeter.

40+15+25+25+15=120 cm, so the perimeter is 120 cm.
