2. Find the perimeter of each figure. (All lines meet at right angles.)
Answers
Answer:
All segments of the polygon meet at right angles (90 degrees). The length of segment AB¯¯¯¯¯¯¯¯ is 10. The length of segment BC¯¯¯¯¯¯¯¯ is 8. The length of segment DE¯¯¯¯¯¯¯¯ is 3. The length of segment GH¯¯¯¯¯¯¯¯ is 2.
Find the perimeter of the polygon.
Correct answer:
46
Step-by-step explanation:
Answer:
Perimeter: The sum of all sides of a figure or a shape is known as the perimeter of that shape. e.g let a shape have five sides of length 5m, 6m, 4m, 7m, 4m, respectively, so the perimeter of that shape will be 5+6+4+7+4 = 26m.
Step-by-step explanation:
There are lots of shapes but some shapes have unique characteristics so that's why there are formulas for the perimeter of these shapes. e.g
Square:
- Square having all sides same,
- The formula for perimeter = 4 × sides.
Rectangle:
- Rectangle has parallel sides equal,
- The formula for perimeter = 2 × ( l + b )
Circle:
- The Circle has fully curved sides
- The formula for perimeter = 2πr
There are many shapes in which all lines meats at right angles some are -Figure 1: Square of side 4m
Perimeter = 4 × sides.
= 4 × 4m
= 16m
Figure 2: Length of rectangle = 5m
Breadth of rectangle = 6m
Perimeter = 2× ( l + b )
= 2 × ( 5 + 6 )
= 2 × 11
= 22m
Figure 3: Figure 3 is given in diagram
Sides of figure 3 are = 12m, 6m, 10m, 5m, 5m, 10m, 6m, 12m
Perimeter = Sum of all sides
= 12m+ 6m+ 10m+ 5m+ 5m+ 10m+ 6m+ 12m
= 66m
