6. If a rectangular piece of dimensions
3 cm x 2 cm is cut from one corner of a
rectangular sheet of dimensions 10 cm x 6 cm
and attached to its side projecting out of
the rectangle, what will be the change in
perimeter of the new shape thus formed?
Answers
Answer:
Answer: Perimeter of new shape = 27 cm.
Step-by-step explanation:
Since we have given that
Dimensions of rectangular sheet is given below:
Length of rectangular sheet = 10 cm
Breadth of rectangular sheet = 6 cm
But according to question, we have mentioned that if a rectangular piece of dimensions 3 cm × 2 cm is cut from one corner of a rectangular sheet
so, Length of new shape will be
\begin{gathered}
10 cm -3 cm=7 cm and 10 cm
end{gathered}
10 cm−3 cm=7 cm
and 10 cm
Breadth of new shape will be
\begin{gathered}6\ cm-2\ cm\\\\=4\ cm\\\\And\ 6\ cm\end{gathered}
6 cm−2 cm
=4 cm
And 6 cm
Perimeter of new shape is given by
\begin{gathered}10\ cm+6\ cm+7\ cm+4\ cm\\\\=27\ cm\end{gathered}
10 cm+6 cm+7 cm+4 cm
=27 cm
Hence, Perimeter of new shape = 27 cm.
Answer:
Perimeter of new shape = 27 cm.
