Question

The base of a parallelogram is four times its height. If the area of the parallelogram is 324 cm², find the base and height. Enter the numerical answers only with the base first, separated by a comma and a space like this; 1, 2

Answer 1

So the base is 45, right?

Answer 2

How did you get that?

Answer 3

nevermind Cal.. I already got it my friend showed me.. but Im still confuse tho...

Answer 4

Ok. The formula for the area of a parallelogram is bh. The base is 4x. The height is x.
\[A = 4x \times x \implies 4x^2\]\[342 = 4x^2\]\[81 = x^2\]\[x = 9\]Therefore, 4x = base
4(9) = base = 36
height = x = 9

Answer 5

yeah I got that too.. well I didnt get that answer, my friend showed me.. lol

Answer 26

The coordinates of the vertices of u25b3ABC are A(1, 1) , B(5, 1) , and C(5, 3) . The coordinates of the vertices of u25b3Au2032Bu2032Cu2032 are Au2032(u22121, u22121) , Bu2032(u22125, u22121) , and Cu2032(u22125, u22123) .

Which statement correctly describes the relationship between u25b3ABC and u25b3Au2032Bu2032Cu2032 ?

A. u25b3ABC is congruent to u25b3Au2032Bu2032Cu2032 because you can map u25b3ABC to u25b3Au2032Bu2032Cu2032 using a translation 2 units to the left and 2 units down, which is a rigid motion.

B. u25b3ABC is congruent to u25b3Au2032Bu2032Cu2032 because you can map u25b3ABC to u25b3Au2032Bu2032Cu2032 using a reflection across the y-axis, which is a rigid motion.

C. u25b3ABC is not congruent to u25b3Au2032Bu2032Cu2032 because there is no sequence of rigid motions that maps u25b3ABC to u25b3Au2032Bu2032Cu2032.

D. u25b3ABC is congruent to u25b3Au2032Bu2032Cu2032 because you can map u25b3ABC to u25b3Au2032Bu2032Cu2032 using a rotation of 180u00b0 about the origin, which is a rigid motion.
