PLEASE HELP QUICKLY Triangle WTC has a perimeter of 33.5 meters. If it is dilated by a scale factor of 4, what will be the effect on the perimeter of the image?

a. The perimeter of the image will be 8 times the perimeter of the pre-image.

b. The perimeter of the image will be 1/4 the perimeter of the pre-image.

c. The perimeter of the image will be 16 times the perimeter of the pre-image.

d. The perimeter of the image will be 4 times the perimeter of the pre-image.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

9987

step-by-step explanation:

15: 24

step-by-step explanation:

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
