The area of a triangular block is 64 sq in. if the base os the triangle is twice the height, how long are the base and the height of the triangle

Define x :

Let the height be x.
Height = x
Length = 2x


Solve for x:

Area of triangle = 1/2 x base x height
64 = 1/2 (x)(2x)
x² = 64
x = √64
x = 8


Find the height and the length:

Height = x = 8 in
Length = 2x = 2(8) = 16 in


The base is 16 in and the height is 8 in.
