If the perimeter of the equilateral triangle is 18 cm then the width of the rectangle be 11.2 cm.

Given that the perimeter of the equilateral triangle be 18 cm and the perimeter of all the three triangles be 46.4 cm.

We are required to find the width of the rectangle.

Rectangle is basically the shape which is having opposite sides equal to each other.

Perimeter of equilateral triangle=3 *side

3* side=18

side=18/3

side=6

Since it is on the length of the rectangle so the length of rectangle be

6 cm.

Perimeter of all the three triangles=2*width of the rectangle+1 length+perimeter of 1 equilateral triangle.

T1 and T2 are the other triangles.

Suppose the width of the rectangle be x.

Perimeter=2*x+6+18

46.4=2x+24

2x=46.4-24

2x=22.4

x=11.2

So,the width of the rectangle is equal to 11.2 cm.

Hence if the perimeter of the equilateral triangle is 18 cm then the width of the rectangle be 11.2 cm.

Explain how to divide an amount by number 3
Greeley [361]

Answer:

Dividing by 3 means splitting a number into 3 numbers, all equal. The division sign can be represented by a /.

For example, 12/3=4. We can check our answer by multiplying our answer by 3, and seeing if we get our original answer.

4*3=12

Division is the opposite of multiplication, so it makes sense that multiplication is a valuable tool to check our work.

Hope this helps!

Find the solution set for the following equation. <img src="https://tex.z-dn.net/?f=-%5Csqrt%28x%29%3D5" id="TexFormula1" title=
andrey2020 [161]

Answer:

Solution set = {25}

Step-by-step explanation:

=> -\sqrt{x} =5

Dividing both sides by -1

=> \sqrt{x} = -5

Taking square on both sides

=> x = 25

<em><u>Solution set = {25}</u></em>

A circular garden has a circumference of
omeli [17]

This solution to this problem is predicated on the fact that the circumference is just: 2\pir. A straight line going through the center of the garden would actually be the diameter, which is well known to be two times the radius of the circle, so we can say that the circumference is just:

d\pi

So, solving for both the radius and the diameter gives us:

d\pi=8xy^2\pi\\ d=8xy^2\\ \\ 2\pi r=8xy^2\pi\\ r=4xy^2

So, the length of thes traight path that goes through the center of the guardain is just 8xy^2, and we can use the radius for the next part of the problem.

The area of a circle is \pi r^2, which means we can just plug in the radius and find our area:

A=\pi r^2 \implies \\ A=\pi (4xy^2)^2\implies \\ A= 16\pi x^2y^4

So, we have found our area(16 \pi x^2 y^4) and the problem is done.
