Answer:
The first one isnt equivalent
Step-by-step explanation:
perimeter = 2L+2W
L=2+w
40 = 2L+2W
40= 2(2+w)+2W
40=4+2w+2w
36=4w
w=9
L=9+2=11
2(9) = 18, 2(11) = 22, 22+18 = 40
L=11
W=9
Area = L x w
area = 11x9= 99 square yards
Answer:
is that thing a less than sign?
Step-by-step explanation:
Answer:
Radius r=0.30m, Velocity, v=36m/s
(a) angular speed w=
