Question
The two figures are similar. Find the ratios (red to blue) of the perimeters and of the areas.
- Perimeter = 11: 6, Area = 121:36
- Perimeter = 6:11, Area = 36:121
- Perimeter = 36:121, Area = 6:11
- Perimeter = 121:36, Area = 11:6
Hint:
ratio of perimeter = ratio of sides
Ratio of area = (ratio of perimeter)2
The correct answer is: Perimeter = 11: 6, Area = 121:36
perimeter = 11:6 and area = 121: 36
We know that ratio of perimeter = ratio of sides
Given, ratio of sides = 11: 6
Ratio of area = (ratio of perimeter)2
Ratio of area = (11/6)^2 = 121:36
Area: The area is the region defined by an object's shape. The area of an object shape is the space covered by a figure or any two-dimensional geometric shape in a plane. All shapes' areas are determined by their dimensions and properties. Different shapes have various areas.Area of Rectangle = a × b
