Answer:

56.1, 36.2

Explanation:

For this we need to use the Pythagorean Theorem, which is a^2+b^2=c^2. We have our a and c values, so we can make the equation 11^2+b^2=15^2, or 121+b^2=225. Next, we isolate b.

121+b^2=225

-121 -121

___ ___

0 104

b^2=104

Now, we have to find the square roots of both sides. If we do this, we get b= 10.2.

Now, we can find our perimeter:

11+15+10.2= 36.2

For area, the formula is 1/2(b)h (1/2 times the base and height), so:

1/210.2=5.1

5.1*11=56.1

Hope this helps!
