Answer:
225 m2
Step-by-step explanation:
area= side*side
= 15x15
225 m2
Answer:
18×18×36
Step-by-step explanation:
According to the Question
108≥ 4h + w
Volume V is given by
V = wh^2
⇒V= (108-4h)h^2
⇒V= 108h^2 - 4h^3
Now differentiating and keeping = 0 we get
V' = 216h - 12h^2 = 0
h = 216/12 = 18
w = 108 - 4×18 = 36
V = 36×18^2 = 11664 from a box of 18×18×36.
It would be subtraction I think
Answer : 50 degree
To find angle 1 , we apply outside angle theorem . Refer to the diagram attached below.
Measurement of arc EF=140 degrees
Measurement of arc GH = 40
Angle D = angle 1
Theorem says

Now we plug in the values

angle 1 = 50
Measurement of angle 1 = 50 degrees
