Question

Please help, me and my friend need help answering this question ;)

Answer 1

`12(8)/(9)` cm

Explanation:

Perimeter of the rectangle = 2(length + width)

length = 3⅚ cm

width =
`2(11)/(18)` cm

Thus:

Perimeter =
`2(3(5)/(6) + 2(11)/(18))`

Change the fractions to improper fractions

Perimeter =
`2((23)/(6) + (47)/(18))`

Add

=
`2((69 + 47)/(18)`

=
`2((116)/(18)`

=
`(116)/(9)`

=
`12(8)/(9)` cm
