Question

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

Answer 1

Answer:

ATQ

Let height is 2x and base is x

Area of traingle =400cm^2

1/2*base *height=400

1/2*2x*x=400

2x^2/2=400

X^2=400

X=20

Now base that is x=20 and height that  is 2x=2*20=40

Hope this is helpful to u then marked it as a brainliest answer

ANSWER :

The Base of the Triangle = b

The Height of the triangle, h = 2b

The Area of the triangle, A = 400 cm^2

We know that ,

$area \: of \: triangle \: = \frac{1}{2} \times b \times h$

From this ,,,

Area , A = 1/2 × b × 2b

400 = b^2

b = ( 400)^1/2

b = 20cm

The height of the triangle, h = 2b

h = 2 × 20

h = 40 cm
