The correct option is second one i.e 24 units.
Therefore the height of the triangle is

Step-by-step explanation:
Given:
An equilateral triangle has all sides equal.
ΔMNO is an Equilateral Triangle with sides measuring,

NR is perpendicular bisector to MO such that
.NR ⊥ Bisector.
To Find:
Height of the triangle = NR = ?
Solution :
Now we have a right angled triangle NRM at ∠R =90°,
So by applying Pythagoras theorem we get

Substituting the values we get

Therefore the height of the triangle is

Total area of the wall = 28 * 12 = 336 ft²
time = 5 1/4 = 21/4 hours
speed = 336 / 21/4 = 64 ft²/hour
