Answer:

48 meters

Step-by-step explanation:

3*4 = 12

5*4 = 20

4*4 = 16

These are the sizes when the triangle enlarges with a scale factor of 4.

To find perimeter, you add the sides together

12+20+16 = 48

The perimeter is 48 meters

A. 9

B. 24

C. 6

D. 16

Step-by-step explanation:

Given ratios are;

A. 2 : 3 = 6 : x

Product of mean = Product of extreme

6*3=2*x\\18=2x\\2x=18

Dividing both sides by 2

\frac{2x}{2}=\frac{18}{2}\\x=9

B. 4 : 7 = x : 42

Product of mean = Product of extreme

7x=168

Dividing both sides by 7

\frac{7x}{7}=\frac{168}{7}\\x=24

C. 2x : 48 = 3 : 12

Product of extreme = Product of mean

2x*12=48*3\\24x=144

Dividing both sides by 24

\frac{24x}{24}=\frac{144}{24}\\x=6

D. 12 : 15 = x : 20

Product of mean = Product of extreme

15*x=12*20\\15x=240

Dividing both sides by 15

\frac{15x}{15}=\frac{240}{15}\\x=16
