Aliun [14]

Answer:

The perimeter of the p triangle = 38.4 cm

Step-by-step explanation:

Given

The perimeter of a triangle z be = 48 cm

The triangle is dilated by a scale factor of 0.8

To determine

What is the perimeter of the triangle after it is dilated by a scale factor of 0.8?

  • As the scale factor < 1, it means the new perimeter will be reduced.

The new perimeter of the triangle p can be calculated by multiplying the perimeter of the original triangle z by 0.8

i.e.

Perimeter of triangle p = 48 × 0.8 = 38.4 cm

Therefore, the perimeter of the triangle p is = 38.4 cm
