Answer 1

Answer:

84.05 square inches

Step-by-step explanation:

Given;

Area of N = 320×(4.1/8)^2 = 84.05 square inches

Answer 2

Answer:

84.05 square inches

Step-by-step explanation:

Given;

Area of M = 320 square inches

Scale factor of M to N = 8 : 4.1

Since M and N are equilateral, it means all 3 sides in triangle M are equal and all 3 sides in triangle N are equal

To find the area of triangle N, we have:

$N = 320 * (\frac{4.1}{8})^2$

= 84.05 square inches

Therefore area of triangle N =

84.05 square inches
