A triangle has side lengths of 3 m, 5 m and 4 m. The triangle is enlarged so that the larger triangle is similar to the original and the scale factor is 4. Find the perimeter of the larger
triangle

The perimeter of larger triangle is 48m.

Given that,

According to the scenario, calculation of the given data are as follows,

Perimeter of larger triangle =  4m ( 3m + 5m + 4m)

= 4m 12m

= 48 m

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

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
