let the height of the parallelogram be x.
then, base of the parallelogram is 3x.
the area is 867cm².
ATQ,
Area of parallelogram = 867cm²
=> b × h = 867cm²
=> 3x × x = 867cm²
=> 3x² = 867cm²
=> x² = 867/3
=> x² = 289
=> x = √289
=> x = 17
therefore, the height of the parallelogram is 17cm.
base of the parallelogram is 3 × 17 = 51cm.
I hope it helps you.

Answer:
height of the parallelogram is 17cm.
Step-by-step explanation:
let the height of parallelogram be h.
b=3h
Area of parallelogram=b×h
867=3h×h
867=3h^2
(867)/3=h^2
289=h^2
√289=h
17cm=h
Hope it's help you!!☺
