a. 2450 cm
b.757.1 cm
c.612.5 cm

Answer 1

Answer:

The answer to your question is 757.1 cm²    

Step-by-step explanation:

Data

Ratio  1: 1.618

long side = 35 cm

Area = ?

Process

1.- Use proportions to solve this problem

       1 : 1.618 :: x : 35

        x = (35 x 1) / 1.618

        x = 35 / 1.618

        x = 21.63

2.- Calculate the area of the rectangle

Area = base x height

Area = 35 x 21.63

Area = 757.1 cm²
