Question

the base and height of a triangle are in the ratio 4 ratio 5 if its area is 1000 centimetre find its base and height​

Answer 1

Step-by-step explanation:

let the base be=4x

height =5x

area of triangle=1/2*4x *5x

90=10x²

x²=90/10

x²=9

x=3

b=4*3=12

h=5*3=15

Answer 2

Answer:

Base = 400 cm

Height = 500 cm

Step-by-step explanation:

Let the height of the triangle = 5x

and the base of the triangle = 4x

Now, area of triangle = 1/2 × base × height = 1000 cm

=> 1/2 × 4x × 5x = 1000

=> 20x/2 =1000

=> 10x = 1000

=> x = 1000/10

=> x = 100

Now, Height = 5x = 5×100 = 500 cm

and Base = 4x = 4×100 = 400 cm
