Answer:
4
Step-by-step explanation:
square root of 16 is 4
Just like the relationship of multiplication and division, square roots and exponents have similar relationship.
Example,
2^2=4
√4 = 2
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
