For this case we use Heron's formula to calculate the area of the building.
We have then:
A = root ((s) * (s-a) * (s-b) * (s-c))
Where,
s = (a + b + c) / 2
Substituting values:
s = (83 + 189 + 178) / 2
s = 225 feet
A = root ((225) * (225-83) * (225-189) * (225-178))
A = 7352.509776 feet ^ 2
Rounding off we have:
A = 7353 feet ^ 2
Answer:
The ground area K covered by the building is:
K = 7353 feet ^ 2
The answer is C hope that helps
Answer:
Step-by-step explanation:
We would evaluate the left hand side of the equation first. The left hand side of the equation contains
- (5-(a+1)) = - (5 - a - 1) = - 5 + a + 1
Next step is to evaluate the right hand side of the equation first. The right hand side of the equation contains
9-(5-(22-3)) = 9-(5-22+ 3) = 9-5+22- 3 = 23
Therefore
- 5 + a + 1 = 23
-4 + a = 23
Adding 4 to the left hand side and the right hand side of the equation, it becomes
- 4 + 4 + a = 23 + 4
a = 27
