Measure of each side of an equilateral triangle is 12cm. it's area is given by
a) 9 root3
b)18 root3
c)27 root3
d) 36 root 3
fast

D

Step-by-step explanation:

The area (A) of an equilateral triangle is calculated as

A = ← s is length of a side

Here s = 12, thus

A =

  =

  = 36 → D

oof cheaters cheat because they’re lazy that’s why i cheat xd

step-by-step explanation:

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
