Answer: D. 1:3
The ratio of the small to the large shaded portion can be written as;
A1 : A2
6 : 18
6/6 : 18/6
1 : 3
The ratio is 1 : 3
If the areas of the 4 squares are 50, 32, 18 and 12, what is the ratio of the small shaded portion to the area of the large shaded portion?A. 1:8
B. 1:6
C. 1:4
D. 1:3
E. 1:1
Attached is the figure
Explanation:
Given;
Area of the squares from the biggest to the smallest is: 50, 32, 18, 12
According to the attached figure, the small shaded portion is the margin between the smallest square and the next square.
The area of the small shaded portion A1 = Area of the next square to the smallest - Area of the smallest
A1 = 18 - 12 = 6
Area of the large shaded portion A2 = Area of the largest square - Area of the next square to the largest
A2 = 50-32 = 18
The ratio of the small to the large shaded portion can be written as;
A1 : A2
6 : 18
6/6 : 18/6
1 : 3
The ratio is 1 : 3
