Last year, the school made a field area for gym with a width of 3 meters and an area of 27 square meters. This year, the school wants to make the gym field area two times as long and two times as wide. What is the length of this years field? The length of this years field is meters.

The length of this years field is 18 meters.

Step-by-step explanation:

GIven: For field,

Width = 3 meters, Area = 27 square meters

Area of rectangular field = Length x width

So, 27 = Length x 3

⇒ Length =

Hence, the length of field last year = 9 m

If this year, the school wants to make the gym field area two times as long and two times as wide.

So, length = 2 x ( previous length) = 2 x ( 9 m) = 18m

Hence, the length of this years field is 18 meters.

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
