The area of a square garden is 900m2. Find
its perimeter.​

120m

Step-by-step explanation:

Each side of square have same length, assume x for one side of square:

x^2=900

x=30

perimeter:30x4=120m

120 square meters

Step-by-step explanation:

Since area is base times height and this is a square, we know all sides are the same length. Take the square root of 900 and you will get 30, meaning each side is thirty meters long. 30 x 4 = 120, that’s your perimeter. Hope this helps! I’m on my phone, so sorry if this explanation is hard to read. Feel free to ask any questions!

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
