We can notice the triangle on the square, hypotenuse is 8m and the base is half of the lengt of the square we will name it x

then

we can use pythagoras to solve

a^2+b^2=h^2

where a and b aer sides of the triangle and h the hypotenuse

replacing

\begin{gathered} x^2+x^2=8^2 \\ 2x^2=64 \\ x^2=\frac{64}{2} \\  \\ x=\sqrt[]{32}=4\sqrt[]{2} \end{gathered}

the length of x is half of the side of the square then the side of the square is

4\sqrt[]{2}\times2=8\sqrt[]{2}

each side of the square is 8v2 meters

Area

we use formula of the area

\begin{gathered} A=l\times l \\ A=8\sqrt[]{2}\times8\sqrt[]{2} \\  \\ A=128 \end{gathered}

<em>area of the square is 128 square meters</em>

Perimeter

we use formula of the perimeter

\begin{gathered} P=4l \\ P=4\times8\sqrt[]{2} \\ P=32\sqrt[]{2} \end{gathered}

perimeter of the square is 32v2 meters

There is a a circle whose circumference is 34.54 cm.
Naily [24]

Answer:

\huge\boxed{Diameter=11cm}

Step-by-step explanation:

Important information:

Circumference of a circle= \pi*diameter

Method:

To work out the diameter, we would need to divide the circumference of 34.54 by pi, which in this case is 3.14, this gives us 11cm. This is because we are simply rearanging the formula of the circumference of a circle to make the diameter the subject.

Step By Step:

1) Rearange the formula to make the diameter the subject.

diameter=\frac{circumference}{\pi}

2) Divide 34.54 by 3.14(\pi).

34.54/3.14=11cm
