Step-by-step explanation:

As equilateral triangle have equal sides

By applying Pathagores theorem

(hyp)^2=(per)^2+(base)^2

by putting values

$(a)^2=(per)^2+( \frac{a}{2} )^2$

$a^2- \frac{a^2}{4} =(per)^2$

by taking lcm on L:H:S

$\frac{4a^2-a^2}{4} =(per)^2$

$\frac{3a^2}{4} = (per)^2$

by taking square root on both side

$\frac{ \sqrt{3}a }{2} =(per)$

i hope u will understand

As a result of such situation, you have reduced your net worth. Before selling the car, your net worth is $12,000-$7,000=$5,000. After selling the car and paying off the loan, it’s $2,000. As you can see it reduced $3,000. Hope this answers the question. Have a nice day.
