Question

?

Answer 1

just multiply like the formula says...

Answer 2

\(\Large Area=15m\sqrt{9m} \cdot \sqrt{3m} \)

Answer 3

can you simplify?

Answer 4

I'm working on the question, hold on.

Answer 5

maybe it'd be better if it's written like this so you can simplify easier:
Area = \(\large 15 \cdot m \cdot \sqrt{9} \cdot \sqrt{m} \cdot \sqrt{3} \cdot \sqrt{m} \)
= \(\large 15 \cdot m \cdot \sqrt{9} \cdot \sqrt{m} \cdot \sqrt{m} \cdot \sqrt{3} \)
= \(\large 15 \cdot m \cdot \color {red}{\sqrt{9} \cdot \sqrt{m} \cdot \sqrt{m}} \cdot \sqrt{3} \)

simplify that in red and you're almost there....

Answer 6

It's d, correct ?

Answer 7

@dpaInc

Answer 8

no... it's not D....
can you just tell me what is that red part i wrote in simplified form?
