The correct answer is D but i don’t understand
iren [92.7K]
The answer depends on the way you solved it.

I am assuming you take the base on which you perceived to be: . 5 and height which is 2.


So you must've ended with 1

But in actuality, you need to use the equation above and plug in 1.5 and 1
Subtract them and you should get 1.25

Do the same to the other side, you should get 6.

.125 x 6  = .875

49/60 = d/200

cross-multiply:

60d = 9800

d = 163.3
