Question

What are the dimensions of the following rectangle?

Answer 1

A. -6 2/3, -18
B. -6 2/3, 6
C. 6
D. 6, 20

Answer 2

A= L times B
Where 'A' is area
'L' is length
'B; is breath or width/(w)

Answer 3

So now
We get
120 = (3x + 2)(x)
Solve for 'x' First.

Answer 4

120 = 3x^2 + 2x

Answer 5

i dont understand how to get the answer?

Answer 6

OKAY!
We will use the first method then.
SO
the eqn we had obtained was
120 = x^2 + 2x
right?

Answer 7

yea

Answer 8

so now
120 = 3x^2 + 2x
equate the eqn to 0

Answer 9

i.e
3x^2 + 2x -120 = 0

Answer 10

On solving we get
x = -20/3 = 6 2/3
and
x = 6

Answer 11

So the correct ans is B
