Answer:

217 sq cm

Step-by-step explanation:

to find the area of the blue portion you can find the area of the entire rectangle and subtract from it the area of the triangle

Area(rectangle) = 21 x 11

A = 231

Area(triangle) = 4(7)÷2

A = 14

Area(blue) = 231 - 14 = 217

Answer:

The area is 217cm

Step-by-step explanation:

area of triagle:

4x7 = 28

28/2 = 14

area of rectangle:

11x21 = 231

Since the triangle is inside the blue you subtract its area from the blue's area.

231-14 = 217

Given the triangle

PQR

with points

P(8,0)

Q(6,2)

R(-2,-4)

And the triangle

P'Q'R'

with points

P'(4,0)

Q'(3,1)

R'(-1,-2)

Part A. Scale factor

Using the vertex

P( 8, 0)

P'(4,0)

the dilatation factor is given by

$\frac{4}{8}=\frac{1}{2}$

The triangle has a dilatation factor of 1/2

Part B:

P''Q''R'' after using P'Q'R' reflected about the y axis

to make a reflection over the y axis

coordinates (x,y) turn into coordinates (-x,y)

as follows

$P^{\prime}(4,0)\rightarrow P^{\prime\prime}(-4,0)$ $Q^{\prime}(3,1)\rightarrow Q^{\prime\prime}(-3,1)$ $R^{\prime}(-1,-2)\rightarrow R^{\prime\prime}(1,-2)$

Then triangle P''Q''R'' has coordinates

P''(-4,0)

Q''(-3,1)

R''(1,-2)

Part C:

PQR is congruent to P''Q''R''?

Congruent triangles are triangles that have the same size and shape. This means that the corresponding sides are equal and the corresponding angles are equal.

Then the triangles are not congruent

Answer:

$\frac{16}{81}$

Step-by-step explanation:

Just Square the numbers like a normal equation.

4² = 16

9² = 81

This gives us $\frac{16}{81}$

or 0.198 as a decimal (approx)
