Question

The perimeter of parallelogram ABCD is 46 inches. What is DA?

Answer 1

x ≈ 5.7 units

Explanation:

Consider the right triangle with legs x and hypotenuse 8

Using Pythagoras' identity

x² + x² = 8²

2x² = 64 ( divide both sides by 2 )

x² = 32 ( take the square root of both sides )

x =
`√(32)` ≈ 5.7 units
