Match the formula with the polygon.
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

Keywords: area, Triangle, square, parallelogram, rectangle, trapezoid, regular polygon, equilateral triangle

A company plans to enclose three parallel rectangular areas for sorting returned goods. The three areas are within one large rec
Svetlanka [38]

Answer:

The largest total area that can be enclosed will be a square of length 272 yards.

Step-by-step explanation:

First we get the perimeter of the large rectangular enclosure.

Perimeter of a rectangle =2(l + w)

Perimeter of the large rectangular enclosure= 1088 yard

Therefore:

2(L+W)=1088

The region inside the fence is the area

Area: A = LW

We need to solve the perimeter formula for either the length or width.

2L+ 2W= 1088 yd

2W= 1088– 2L

W = \frac{1088-2L}{2}

W = 544–L

Now substitute W = 544–L into the area formula

A = LW

A = L(544 – L)

A = 544L–L²

Since A is a quadratic expression, we re-write the expression with the exponents in descending order.

A = –L²+544L

Next, we look for the value of the x coordinate

L= -\frac{b}{2a}

L= -\frac{544}{2X-1}

L=272 yards

Plugging L=272 yards into the calculation for area:

A = –L²+544L

A(272)=-272²+544(272)

=73984 square yards

Thus the largest area that could be encompassed would be a square where each side has a length of 272 yards and a width of:

W = 544 – L

= 544 – 272

= 272 yards
