Answer:
area of the rectangle is ≈757.1 cm²
Step-by-step explanation:
To find the area we first need to find the other side length, since the first length is given as 35cm
But the question says they are in the ratio 1 : 1.618
Let x be the breadth of the golden box
1 : 1.618
x : 35cm
1/1.618 =x/35
cross multiply
1.618x = 35
Divide both-side of the equation by 1.618
1.618x/1.618 = 35/1.618
x = 21.632
Therefore the breadth is 21.632
Area of the rectangle = l × b
Area of the rectangle=35 × 21.632
Area of the rectangle = 757.12 cm²
Therefore; area of the rectangle is ≈757.1 cm² to the nearest tenth.
