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

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
