Find the area of the parallelogram below by decomposing into two triangles. The figure is not drawn to scale.

Step-by-step explanation:

area of a triangle = (½)(base)(height)

You can divide the parallelogram into two congruent triangles with base = 8 mi and height = 10 mi.

area of each triangle = (½)(8)(10) = 40 mi²

area of parallelogram = 2(40) = 80 mi²

step-by-step explanation:

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
