The length of one side is 12√3.
We know that the area of a triangle is given by the formula:
A=1/2(b)(h)
We can substitute the area in:
108√3 = 1/2(b)(h)
Let b be the side of the equilateral triangle. To find the height, we will use the Pythagorean theorem. We know that the height bisects the base, so we will call that leg of the right triangle formed (1/2b). Since the triangle is equilateral, we will call the hypotenuse b as well. We now have:

We will now substitute this in the formula for area we had above:
108√3=(1/2)(b)(√3/2b)
108√3=√3/4b²
Multiply both sides by 4:
(108√3)×4=(√3/4b²)×4
432√3=√3b²
Divide both sides by √3:
432√3/√3 = √3b²/√3
432=b²
Take the square root of both sides:
√432=√b²
Simplifying the radical, we have 12√3.
Answer:
28+104 = 132cm^2
Step-by-step explanation:
We can find the area of this figure by breaking it into two separate pieces. The top is a rectangle and the bottom is a trapezoid.
A rectangle = l*w = 7*4 = 28 cm^2
A trapezoid = 1/2 (b1+b2) *h = 1/2 (19+7) *8 = 1/2 (26)*8 =104 cm^2
Add these areas together
28+104 = 132cm^2
I think the answer would be the first one
Answer:
In this problem, if we solve it by linear programming one of the conditions does not satisfy which is - number of B should be produced at least 180 in order to meet backlog. This means for B only we need 180* 4 = 540 lbs of iron where as daily supply is only of 100 lbs.
for this option (3) looks viable i.e. 3A + 4B <= 100
