Question

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

​

Answer 1

Answer:

base is 20 cm and height is 40 cm

Step-by-step explanation:

Lets assume that the base is'x'cm

the height will be'2x'cm

area of triangle =400cm^2

1/2×X×2x=400cm^2

x^2=400cm^2

x=√400cm^2

x=20cm

height =2x=2×20=40cm

thank you...

Answer 2

Let the base be y. so height will be 2 times of base which is 2y.

and area is 400cm^2

we know,

area off triangle = 1/2 ×base×height

400cm^2 = 1/2 × y × 2y

400cm^2 = y^2

√400cm^2 = y

20cm y

so,

base = 20cm

and height = 2y = 2×20cm = 40cm
