Question

In a triangle the height is double the base and the area is 400cm.find the length of the base and height

Answer 1

ANSWER⭐⭐❣❣

Let the base be Xcm

Given Area=400cm

According to question,

Height=2Xcm

Now, 1/2*X*2X=400

1/2*2X^2=400

X^2=400

X=

$\sqrt{400}$

X=20

So, Base=20cm and Height=2*20=40cm

HOPE IT HELPS YOU✔✅✨✨✌✌

Answer 2

let the base of th e triangle be b

let the height of the triangle be h

2b=h

now,

area of triangle =1/2*b*h

400cm*2=b*2b

800/2=b^

400=b^

b=20

h=40
