Answer:
Step-by-step explanation:
Given that ,
1) A square with a side that measure 7 dm.
2) A rectangle with length of 5 cm and a width of 3 cm.
3) A hexagonal lot with 4 m, 5 m, 6 m, 7 m, 8 m, and 2 m dimensions of each side.
4)A triangle with sides that measure 4 cm, 5 cm, and 4 cm.
5) A pentagon with sides of 2 cm, 2 cm,4 cm,4 cm and 5 cm.
So,
1) Perimeter of square = ( 4 × a )
= ( 4 × 7 )
= 28 dm.
2) Perimeter of rectangle = 2 × ( l + b )
= 2 × ( 5 + 3 )
= 2 × 8
= 16 cm.
3) Perimeter of hexagonal = ( sum of all side length )
= ( 4 + 5 + 6 + 7 + 8 + 2 )
= 32 m.
4) Perimeter of triangle = ( a + b + c )
= ( 4 + 5 + 4 )
= 13 cm.
5) Perimeter of Pentagon = ( sum of five side length )
= ( 2 + 2 + 4 + 4 + 5 )
= 17 cm.
