The base of a parallelogram is 3 times the parallelogram's height. If the base is 21 inches, what is the area?
The area is |
in.2

let height of ||g be 'b', then base of ||g be 3b.

area of ||g=base×height

75cm

2

=3b×b

b

2

=25

b=5cm, therefore height =5cm

Step-by-step explanation:

the height

=21 inches×3

=63 inches

the area

=(21×63)inches

=1323 in.2

answer: i wpould go with c

step-by-step explanation:

it's a proportional graph.

step-by-step explanation:

8 x 5 = 40         (and you have -8x and -5y)

x= absiss

y= orderly

so you have a proportional graph.
