Let, the width = w
We know, A = 2(lw + wh +hl )
250 = 2(10w + 5w + 50)
250 = 2(15w + 50)
250 = 30w + 100
30w = 250 - 100
w = 150/30
w = 5
In short, Your Answer would be Option C) 5 cm

Answer:
36π
Step-by-step explanation:
the formula of the area of the circle is πr^2
if the radius is 6, then its 6*6*π which is 36π
For this case we must factor the following expression:

We rewrite the middle term as a sum of two terms whose product is

And whose sum is

These numbers are:
-5 and -3
So:

We factor the maximum common denominator of each group:
We take common factor

Answer:
