Find x - y subtracted from 0

alexandr1967 [171]

The expression you want to simplify is 0-(x-y).
0-(x-y)
=-(x-y)
=-x+y

You just have to treat the negative sign in front of (x-y) as a -1 and distribute it to both x and -y.

Find the area of the rhombus

MAXImum [283]

<h3> Solution :-</h3>

Area of rhombus :-

$\bf \star \: \: \boxed{ \bf \dfrac{d_{1}d_{2}}{2} }$

$\sf \longrightarrow d_{1} = 4 \sqrt{3} + 4 \sqrt{3} = 8 \sqrt{3}$

$\sf \longrightarrow d_{2} = 4 + 4 = 8$

Area of rhombus :-

$: \implies \sf \dfrac{8 \sqrt{3} \times 8 }{2}$

$: \implies \sf 8 \sqrt{3} \times 4$

$: \implies \bf 32 \sqrt{3} \: {m}^{2}$
