In a equilateral triangle, all sides are equal.
hence each slant side = 12cm
to find the height of the triangle :
use Pythagoras’ Theorem (A^2 + B^2 = C^2)
A = height
B = 6
C = 12
A^2 = 108
A = 10.392... (5s.f.)
area = ½ x base x height
= ½ x 6 x 10.392...
= 31.176
= 31.2 (3s.f.)

Step-by-step explanation:
This is because the amount of bananas could affect the number of ripe avocados.
Answer:
B) Yes
Step-by-step explanation:
Find the least common multiple (LCM) of the denominators in order to find the least common denominator (LCD).
The least common denominator is 7.
Multiply the mantissas: 4.2 x 3.7 = 15.54, add the exponents 5+6= 11 so 15.54 x 10^11, BUT WAIT, there can only be one digit in from to the decimal, so 1.554 x 10^12 (add 11 + 1 decimal place change, so 12)
