Question

The formula for the area of a rhombus is A = a equals StartFraction one-half EndFraction d 1 d 2.d1d2, where d1 and d2 are the lengths of the diagonals.

Which are equivalent equations? Select two correct answers.

d1 = 2Ad2
d1 = d 1 equals StartFraction 2 A Over d 2 EndFraction.
d2 = d 2 equals StartFraction d 1 Over d2 A EndFraction.
d2 = d 2 equals StartFraction 2 A Over d 1 EndFraction.
d2 = 2Ad1

Answer 1

Answer:

Step-by-step explanation:

A = $d_{1}$×$d_{2}$ / 2  ===> 2A = $d_{1}$×$d_{2}$  ===> $d_{2}$ = 2A / $d_{1}$

A = $d_{1}$×$d_{2}$ / 2  ===> 2A = $d_{1}$×$d_{2}$  ===> $d_{1}$ = 2A / $d_{2}$  

From choices you provided, the answers are:

1). d1 = d 1 equals StartFraction 2 A Over d 2 EndFraction.

2). d2 = d 2 equals StartFraction 2 A Over d 1 EndFraction.
