Question

The sides of AABC are 30 units, 40 units, and 60 units long. The corresponding sides of AXYZ are r times as long as the sides of AABC.

The expression that gives the perimeter of AXYZ is:

A. 130/r
B. 130r
C. 130r²
D. 65r

Answer 1

The expression that gives the perimeter of AXYZ is 130r.

Step-by-step explanation:

The perimeter of a polygon is the sum of the lengths of its sides. In this case, the sides of AABC are 30 units, 40 units, and 60 units long. The corresponding sides of AXYZ are r times as long as the sides of AABC. So, the perimeter of AXYZ would be (30r + 40r + 60r) = 130r.
