Question

2) In a triangle the height is double
the base and the area is 400 m² hind
the length of the base and height​

Answer 1

Step-by-step explanation:

let base = b

height= 2b

1/2*b*h= area of triangle

1/2*b*2b= 400 m²

1*b*b= 400 m²

b²= 400 m²

b= √400 m²

= 20 m

base= b= 20 m

height= 2b = 2*20m = 40m

Answer 2

Answer:

Area of the triangle = 1/2 L×B....But the base is twice the height ⇒L=2B

∴400m²= 1/2 ×2B×B⇒

400m²= 1/2B²⇒

√800m²/2 =B⇒

B=20 ∴L=40
