7 Raja is laying tiles on a path that forms
ser-zykov [4K]

Answer:

The perimeter of the garden is 400 feet.

Step-by-step explanation:

Consider the provided information,

Raja is laying tiles on a path that forms   the diagonal of a square garden. If Raja is  told that the length of the diagonal path is  100\sqrt{2}

The length of the diagonal of a square garden is 100\sqrt{2}

Let x represent the side of square.

By Pythagorean theorem we know: a^2+b^2=c^2

Where c is hypotenuse.

The diagonal of the square divides the square into two right angle triangle.

Where, the sides of the square are the legs of the triangle and diagonal is the hypotenuse of the triangle.

x^2+x^2=(100\sqrt{2})^2

2x^2=(100\sqrt{2})^2

x=100

Hence, the side of the square is 100 ft.

The perimeter of the square is 4s where s is the side of square.

4(100)=400

Hence, the perimeter of the garden is 400 feet.

What are the values of x and y?
tresset_1 [31]

Step-by-step explanation:

y is easy.

it is the Hypotenuse (baseline) of the small right-angled triangle created by the height (8) of the main triangle, the segment 6 of the main Hypotenuse and y.

so, Pythagoras :

y² = 8² + 6² = 64 + 36 = 100

y = 10

x is a bit more complex.

I think the easiest way to get it is to know that the height of a right-angled triangle to the Hypotenuse is the square root of the product of both segments of the Hypotenuse.

so, if we call the segments of the Hypotenuse a and b with a = 6, we have

x = a + b = 6 + b

height (8) = sqrt(a×b) = sqrt(6b)

therefore,

6b = height² = 8² = 64

b = 64/6 = 32/3 = 10 2/3 = 10.66666666...

so,

x = 6 + 10.66666... = 16.666666666...

round it to what is needed. e.g. 2 positions after the decimal point (hundredths) ? then it would be 10.67
