Answer:
Dimensions will be
New Length= x/16 units
New width = y/2 units
Area=xy/32 square units
Step-by-step explanation:
Lets assume the dimensions of the school gym to be ;
Length= x
width= y
Length and width are first bisected for a fair.This means by a half
Length will be =x/2
Width will be =y/2
Then the length is divided to form 8 sections that are equal, which will ;
(x/2)÷8
x/2 * 1/8 = x/16 units
New length = x/16 units in dimension
New width will be y/2 units in dimension
Area of each section will be;
length by width
(x/16 )*(y/2)
=xy/32 square units

Answer:
-1/4 meter per minute
Step-by-step explanation:
Since, the volume of a cube,
Where, r is the edge of the cube,
Differentiating with respect to t ( time )
Given, 
Also, V = 8 ⇒ r = ∛8 = 2,
By substituting the values,
Hence, the rate of change of an edge is -1/4 meter per minute.
