The remaining area that the grass will cover will be given by:
Area=[area of rectangle]-[area of the triangle]
area of rectangle will be:
A1=length*width
=20*8
=160 square feet
The area of the triangle will be:
A2=1/2absin theta
since the triangle is equilateral, all the angles are equal and the size of each angle is 60°. Thus the area will be:
A2=1/2*5*5sin 60
=18.3
thus the remaining area of the grass will be:
Area=160-18.3
=149.7 square feet
Answer:
18.52%
Step-by-step explanation:
Relative error can be described as the ratio of the measured absolute value to the actual value
relative error = (stated age - actual age) / actual age x 100
(32 - 27) / 27 x 100
5 / 27 x 100 = 18.52%
Answer:
b = 11 m
l = 44 m
Step-by-step explanation:
l = 4b (length is four times width)
Perimeter = 110 m
2 * ( l + b ) = 110
2 * (4b + b ) = 110
2 * 5b = 110
b = 110 / ( 2*5) = 11
b = 11 m
l = 4b = 4 * 11 = 44 m
Answer:
km
Step-by-step explanation:
One hour has 60 minutes. Therefore, we multiply,
Now, convert meters to kilometers. Divide value by 1000.
