B = 2h

Area = 121
1/2 × b × h = 121
1/2 × 2h × h = 121
h × h = 121
h^2 = 121
h = square root of 121
h = 11

The height is 11 kilometers

P= 2(i+w) what is the solution for I?
Dafna11 [192]

First you had to switch sides of equation.

2(i+w)=p

Then you divide by two from both sides of equation form.

\frac{2(i+w)}{2}= \frac{p}{2}

Simplify.

i+w=\frac{p}{2}

Next, subtract by i from both sides of equation form.

i+w-i=\frac{p}{2}-i

Finally, simplify by equation.

w=\frac{p}{2}-i

Final answer: \boxed{w=p/2-i}

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.
