Papessa [141]

Answer:

37.7 feet

Step-by-step explanation:

Given that:

Measurements of Frankie's yard = 20ft x 32ft

He wants to build a path from one corner to another.

To find:

The length of path = ?

Solution:

Let us consider a rectangle ABCD as shown in the attached image in the answer area.

We are given the two adjacent sides of a rectangle and we have to find diagonal of the rectangle.

To find the diagonal, we can use the Pythagorean Theorem.

We are given the base and perpendicular of the right angled triangle and we have to find the hypotenuse.

According to Pythagorean theorem:

\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}

Diagonal = 20^2 + 32^2\\\Rightarrow Diagonal = 400 + 1024\\\Rightarrow Diagonal = \bold{37.7\ ft}

20 points!! I need help
zaharov [31]

Answer:

11.33 * 16.33 meters to the nearest hundredth.

Step-by-step explanation:

Let the width of the pool be x meters, then the length is x+5 meters.

The length of whole area = x + 5 + 2(3)  = x + 11 meters and the width is

x + 2(3) = x + 6 meters.

So we have the equation (x + 6)(x + 11) = 387.

x^2 + 17x + 66 = 387

x^2 + 17x - 321 = 0

x =  [-17 +/- sqrt (17^2 - 4*1*-321)] / 2

x = 11.33 meters

So the width is 11.3 m and the length is 16.33 meters.
