Question

the ratio of altitude and bass of a parallelogram is 1:2 and area is 18sq.m. find its base and altitude ​

Answer 1

Answer:

Step-by-step explanation:

let the altitude be x and base be 2x as it is in ration 1:2

we know that area of a parallelogram=base×height

18=b×h

18=2x × x

18=2x²⇒ x²=9 ⇒ x=3 (-3 is neglected as length cannot be negative)

so base=2x=2×3=6

and altitude=x=3

so base=6m and altitude=3m

Hope this helps you my friend

pls mark as brainliest :)

thanks :D
