Rachel has a ribbon that is 16.2 metres long. Sheena has a ribbon that is 8.3 metres shorter than Rachel's ribbon. What is the total length of the two ribbons?

24.1m

Step-by-step explanation:

We have these informations to answer this question with.

Length of Rachel's ribbon = 16.2 m

Sheena's ribbon = 8.3m shorter than Rachael's

So,

Sheena's ribbon = length of Rachael's ribbon - 8.3m

= 16.2m - 8.3m

= 7.9m

The total length of the two ribbons

= length of Sheena's ribbon + length Rachael's ribbon

= 16.2 + 7.9

= 24.1 m

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
