Given area of square field =0.25 hectare
1 hectare =10,000m =0.25×10,000 =0.25×100 =2500 sq. m
Let side of square be 'a'
Area of square =a 2 a 2 =2500 ⇒a=50m
Diagonal of square = 2 a= 2 ×50=50 2 m.
Answer:
Step-by-step explanation:
AR = QR = RS = (1/2) QS = 3
So ....by the Pythagorean Theorem, AS = AQ =
√ [3^2 + 3^2] = √[9 + 9 ] = √18
And the area of the two semi-circles= the area of a circle with a radius of AS/2 =
pi [AS/2]^2 =
pi [√18/2]^2 = 18pi/4 = (9/2)pi units^2
And the area of the rest of the figure is just that of a rhombus =
The product of the diagonals / 2 =
AB*QS/2 = 9 * 6 / 2 = 27 units^2
So....the total area =
[(9/2) pi + 27] units^2 = about = 41.1 units^2 [rounded]
Answer: 1%
Step-by-step explanation: Total 2,000
BioChem Lab: 25% of total = 25% . 2000 = 500
LabRep: 45% of Lab = 45% . 500 = 225
There will be 9 LabRep: 225/9 = 25
Participation: 10% of LabRep = 10% . 25 = 2.5
Actual LabRep: 90% of LabRep = 90% . 25 = 22.5
So, each lab report is worth 22.5 of 2000 = 2.5/2000 = 0.01125 = 1.125%
Nearest whole number = 1%
