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
