1 the perimeter of each four​

Answer 1

Answer:

• the perimeter of triangle=sum of all sides of the triangle=8.5+6.2+4.9=19.6cm
• the perimeter of square=4*sides=4*7.9=31.6cm
• the perimeter of rectangle=l*b=46*23=1058cm

Answer 2

Step-by-step explanation:

perimeter of triangle = sum of all sides

= 8.5+6.2+4.9= 19.6 m

perimeter of square = 4*side

=4*7.9 = 31.6m

perimeter of rectangle = 2(l+b)

= 2(46+23)

= 2(69)

= 138m

perimeter of rectangle = 2(l+b)

= 2(49.9+51.1)

= 2(101)

= 202 m
