Question

In a triangle the height is double the base and the area is 4 cm square find the length of the base and height

Answer 1

let base of the triangle be "x"

then height will be "2x"

and area of the triangle is "4 cm sq"

1/2×b×h=4

1/2(x)(2x)=4

2x^2/2=4

x^2=4

then x=2

therefore the length of the base is "2cm"

And the length of the height is "4cm"

Answer 2

Answer:

Step-by-step explanation:

Let the base length is X. So height is 2X. ,Now. Area =1/2× base × height= 1/2× (X) ×(2X)=4cm. X²=4. X=–2,+2. Length will not be negative so X=+2. Hence. Base length=2cm. And height=2×2=4cm.
