A square has an area of 50 square feet what is the perimeter of the square rounded to the nearest foot

28 feet

Step-by-step explanation:

area of a square = side times side; the sides are equal

50 = side times side or 50 = side^2

sqroot of 50 = sqroot of side^2

7 feet is about the size of the side of the square so using that information..

2 length + 2 width or 4 side

4 times 7 = 28

the perimeter is 28 feet

log7 + log7 − log7 = + log7

This is correct answer

Step-by-step explanation:

Explanation:-

we will use properties of logarithm

first property

i) log (ab) = log a + log b

second property  

ii)

Third property

iii)

Now given log7 +log7 - log7

                                           = log(7X7) - log7 ( used first property)

                                           = log(49)- log(7)

                                           =        (used second property)

                                          = + log(7)
