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
15 1/2
Step-by-step explanation:
multiply 1 1/2×6
then multiply 1×5
then multiply 1/2×3
then add all the sums together

Answer:
Step-by-step explanation:
Circumference of circle = length of the wire
2πr = 50 cm
2 * 22/7 * r = 50
2*22*r = 50*7 = 350
r = 350 / 2 * 22
r = 175/22 cm
Area of the circle = πr²
= 22/7 * (175/22)²
= 22 * 175 *175 / 22 *22 *7
= 175 * 175/22*7 = 25 * 175 /22
= 4375/22
= 198.86 cm²
Answer:
cube root of 123 (approx 4.97)
Step-by-step explanation:
volume of a cube is LxWxH, and since it is a cube, all measurements are equal
