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

Dharmesh has a square garden with the perimeter of 132 feet is the area of the garden greater than 1000 square feet
k0ka [10]
Yes, the area of the garden is greater than 1000 sq. ft.

132 = total perimeter
A square has 4 sides
132/4 = 33
A= LxW
A= 33 x 33
A= 1089 sq. ft.

For her exercise today, Keiko plans to both run and swim. Let r be the number of laps she runs and let s be the number of laps s
DerKrebs [107]

Answer:

5r + 3s ≥ 30

Step-by-step explanation:

We know Keiko wants to do exercise at least 30 minutes a day, and she wants ideally to mix up the activities, by combining running and swimming into her schedule.

Since each lap she runs takes 5 minutes and each lap she swims takes 3 minutes, these will be the left side of the inequality:

5r + 3s

She wants to exercise at least 30 minutes a day, so...

5r + 3s ≥ 30

she could do 3 laps of running and 5 laps of swimming for example.
