Answers
Given : Figure
To Find :
1) What is the perimeter of shape B?
2) Which shape's perimeter is less? Shape A or shape D.
3) Area of which shape is more?
4) Area of which shapes are equal?
5) Which shape has equal perimeter and area?
Solution:
perimeter of shape B = 2 (5 + 2) = 14 units
Area = 5 * 2 = 10 sq units
perimeter of Shape A = 7 + 3 + 2 * 2√2
= 10 + 4√2 = 15.66 units
Area = (1/2)(7 + 3) * 2 = 10 sq units
perimeter of Shape D = 4 x 4 = 16 units
Area of shape D = 4 * 4 = 16 Sq units
perimeter of Shape A is Less than Shape D
Perimeter of Shape C = 10 + 4√2 = 15.66 units
Area of Shape C = 2 ( 1/2) ( 5 + 7)* 1 = 12 sq units
Area of shape D is more
Area of A & B are Equal
Which shape has equal perimeter and area - Shape D
