Answer:
The answer to your question is 757.1 cm²
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
