Allisa [31]

Answer:

26 units

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, dilation and reflection.

If a point A(x, y) is reflected across the y axis, the new point is A'(x, -y).

The reflection of the point (-2,-4) across the x axis gives (-2, 4) while the reflection of (3, -4) gives (3, 4)

The distance between (-2, -4) and (-2, 4) is the length while from (-2, -4) to (3, -4) is the breath. Hence:

$Lengthth=\sqrt{(-2-(-2))^2+(-4-4)^2}=\sqrt{64}=8\\ \\Breadth=\sqrt{(-2-3)^2+(-4-(-4))^2}=\sqrt{25}=5$

Perimeter of rectangle = 2(length + breath) = 2(8 + 5) = 2(13) = 26 units

The length of a rectangle, I, is six meters more than it's width, w. If the perimeter of the rectangle is 36 meters what is the

AVprozaik [17]

Answer:

Length = 12 meters

Step-by-step explanation:

Rectangle

Perimeter P = 2(L + W)

The length of a rectangle, I, is six meters more than it's width, W.

Then L = W + 6

P = 2(W + 6 + W)

P = 2 (2W + 6)

P = 4W + 12

Plug in P = 36 meters

36 = 4W + 12

4W = 36 - 12

4W = 24

W = 6 meters

L = 6 + 6

L = 12 meters

Karl cuts a piece of paper into an isosceles right triangle with a perimeter of 27 inches. If the longest side measures 11 inche

Sphinxa [80]

Answer:

Area = 32 square inches

Step-by-step explanation:

It is given that ,

1). an isosceles right triangle with a perimeter of 27 inches

Then the base and height are equal

2). the longest side measures 11 inches

<u>To find the smaller side</u>

Then sum of other 2 sides = 27 - 11 = 16

Base = height = 16/2 = 8 inches

<u>To find the are of triangle</u>

Area = 1/2 * Base*Height

Base = 8 inches and Height = 8 inches

Area = 1/2 * 8* 8 = 32 square inches
