Question

the base of a parallelogram is thrice its height if the area of the parallelogram is 243 CM^2 find its base and height​

Answer 1

Answer:

9 cm and 27 cm.

Step-by-step explanation:

area: 243 cm^2

let the height of the parallelogram be a cm.

then base would be 3a cm.

area of parallelogram = Base x Height

243 = 3a x a

243 = 3a^2

243/3 = a^2

81 = a^2

a = √81

a = 9cm

then, 3a = 3* 9

= 27 cm
