Question

the ratio of base and height of a triangle is 1:2, and its area is 49 sq.cms. find its base and height.​

Answer 1

S O L U T I O N : -

Given ratio of base and height

= 1:2

Let us assume base and height like this

base = X

height=2X

Area of triangle= 1/2×base× height

According to question,

1/2×x×2x=49sq.cm

$x^2$=49sq.cm

x=7 sq.cm

Base = 7 sq.cm (x)

Height=14 sq.cm(2x)

Answer 2

Hola mate:☺As u asked for the question here is the answer ;
As in ∆triangle we know

Area=1/2×base×height.


So we have ratio of base n height and area so we can put it in formula discussed above:


So let:
Base =Bhv
N height=2Bhv


Formula;

49=1/2×bhv×2bhv
49=Bhv²
Bhv=+-7



So now put it in bhv


base=bhv=7 cms
Height=2bhv=7×2=14cms.
