kherson [118]

Step-by-step explanation:

Lets sort out the areas of the polygons to match the areas with the corresponding polygons.

1. Triangle

The formula of the area of the triangle will be:

A\:=\:\frac{1}{2} \:\:b\:h

where b is the base and h is the height of the given triangle

2. rhombus

The formula of the area of the rhombus will be:

A\:=\:\frac{pq}{2}

where p and q being the diagonals

3. Parallelogram

The formula of the area of the parallelogram will be:

A = bh

where b is the base and h is the height

4. square

The formula of the area of the square will be:

A\:=\:s^2

where s being the length if any side, as all sides are equal in square

5. trapezoid

The formula of the area of the trapezoid will be:

A\:=\:\frac{1}{2}\:h\left(b1\:+\:b2\right)

where h is the height and b1 and b2 being the bases.

6. regular polygon

The formula of the area of the regular polygon will be:

A\:=\:\frac{\left(ap\right)}{2}

where a is the apothem and p is the perimeter.

7. equilateral triangle

The formula of the area of an equilateral will be:

A\:=\:1/4\:s^2\:sqrt\left(3\right)

where s is the length of one side of the triangle

The perimeter of a rectangle is 64 inches. Find the value of x if the width is 22 inches and tenth is 2x inches.
Dmitry [639]

Answer:

5

Step-by-step explanation:

Did you mean length instead of tenth? If so, 22*2=44, 64-44=20, 20/2=10. The length of the rectangle is 10 so to find the value of x, divide 10 by 2 so, 10/2=5, and x is equal to 5. : )
