Answer:
length is 40 and breadth is 20
Step-by-step explanation:
120 =2( l + b )
120 = 2( 2x +x )
120= 2 x 3x
120 =6x
120/6 = x
20 = x
length=2x = 2 x 20 = 40
breadth= x = 20.
hope it helps u
2arctan(2/5) = 44°
180° -44° = 136°
The angles are 44°, 136°.
It should end in between 8 and 10 so it'd be considered 9
