Question

the base of a parallelogram is 9 cm and the area is 54cmsquare .find the height of the parallelogram​

Answer 1

Answer:

Area of llgram = B × H

54 = 9 × H

Height (H) = 54/9

(H) = 6 cm

Thus, height of llgram is 6 cm.

Answer 2

The height of parallelogram is "21 cm" and base is "7 cm".

Step-by-step explanation:

$Let \ the \ height \ of \ a \ parallelogram \ be \ "x".\\The \ base \ be \ "\frac{1}{3}x"\\Area,A=147 \ cm^2\\\\As \ we \ know,\\\\The \ Area \ of \ parallelogram,\\A=base\times height\\ On \; putting \ the \ values \ in \ the \ above \ expression,we \ get\\\\147=\frac{1}{3}x\times x\\ \\441=x^2\\\\x=\sqrt{441}\\ \\x=21\\\\Now,\\The \ height=21 \ cm\\The \ base=\frac{1}{3}\times 21=7 \ cm$
