The area of the top of a square table is 240 . What are the dimensions of the top? Round your answer to the nearest hundredth.

Step-by-step explanation:

This problem is on the mensuration of flat shapes, this time a square shape.

we know that the area of a square is given as

area= length*length

area= l^2

from the problem   the area is given as

area= 240 units^2

substitute area for the area in the equation and then we solve for length we have

240= l^2

squareing both sides we have

√240= l

l= 15.49 units

to the nearest hundreths it is

15.5 units

b) the dogs need to shift their focus to human scent.

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
