Two triangles aresimilar. The length of a side of one of the triangle is 6times that of the corresponding sides of the other. Find the ratio of the perimeter and the area of the triangle

--- of perimeters

--- of areas

Step-by-step explanation:

Given

Represent the sides of the first triangle with x, y and z

The sides of the second triangle will be 6x, 6y and 6z

Solving (a): Ratio of perimeter.

The perimeter of the first is:

The perimeter of the second is:

Factorize:

The ratio is:

Cancel out x + y + z

Solving (a): Ratio of Areas.

If the height of the first is h and the base is b.

The height of the second will be 6h and the base, 6b.

The area of the first is:

The area of the second is:

The ratio is:

Divide by 0.5bh

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7
