Question

the ratio of altitude and base of a parallelogran is 1:2 and area is 18 sq m find the base and altitude

Answer 1

let the altitude be x than base equal to 2x

now according to question
area=altitude×base
18=x×2x
18=2x^2
18/2=x^2
9=x^2
x=sq.root(9)
x=3 and -3
we take x=3 because distance is always positive.

so altitude=3
base =2×3=6

pls mark it as brainliest

Answer 2

Ratio = 1:2
Therefore Let height be x and base be 2x.
Given is that area = 18sqm.

Area of a Parellogram = Base × Height
$18 = 2x \times x$
$= 18 = {2x}^{2}$
$= 18 \div 2 = {x}^{2}$
$9 = {x}^{2}$
$x = 3$
Therefore height of the parallelogram = 3m
And Base of the parallelogram = 3 × 2 = 6m
