Question

given that the rectangle above has an area of 48 square units, find m angle klj. round the answer to the nearest hundreth.
a. 18.43 degrees
b. 36.87 degrees
c. 41.41 degrees
d. 48.59 degrees

Answer 1

Answer 2

ok, so first of all KJ = LM = 6, right?

Answer 3

ok yea

Answer 4

And similarly we can say KL = JM. Let's call them \(x\)
So we can say:


Now we know that the area of the rectangle is \(48_{cm^2}\)
So \(6_{cm} \cdot x = 48_{cm^2}\)
can you find \(x)?

Answer 5

*can you find \(x\)?

Answer 6

42?

Answer 7

no because it's not 6 + x = 48
it is 6*x = 48
you have to divide both sides by 6. we get
$$
x = \frac{48_{cm^2}}{6_{cm}} = \frac{48_{cm}}{6}
$$
what is 48/6?

Answer 8

8

Answer 9

right, so \(x = 8_{cm}\)
Now let's redraw this:
