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.

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
