The backyard of a house is a square whose area is 900 square meters. how much fencing is needed to enclose the yard? i'm not sure how to get the answer.

hello!

so area of a square is calculated by this equation

s^2 = a

which means if you multiply two sides together you get the area

what you want to do now is to find a side of the square

plug in the 900 square meters

s^2 = 900

square root both sides to isoate the variable

s = 30 meters

this means that one side is 30 meters

since it is a SQUARE all four sides are equal

just multiply 30 by 4 and that will get the amount of fencing you'll need

30*4 = 1200 meters

you will need 1200 meters of fencing

WAIT

there is a possibility that one side of the house has already enclosed one side of the fence

so if that's the deal then

30*3 = 900meters

IF ONE SIDE OF THE HOUSE IS ALREADY ENLCOSING ONCE SIDE THEN YOU WILL NEED 900 meters of fencing.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
