Question

the altitude of a parallelogram is one third of the base if the area of is 243 centimetre square find the altitude​

Answer 1

Answer:

Step-by-step explanation:

Let the base be x and the altitude be x÷3

Area of parallelogram=Height×Base

243=x(x/3)

243=x²/3

x²=729

x=√729

x=27

Altitude=x/3=27/3=9cm
