Sagot :
the correct question is
What is the perimeter of a rectangle that is 2m 10cm by 45cm?
we know that
The perimeter of a rectangle is equal to
[tex] P= 2L+2W [/tex]
where
L is the length of the rectangle
W is the width of the rectangle
In this problem we have
[tex] L=2\ m\ 10\ cm = 200\ cm+10\ cm=210 \ cm \\ W=45\ cm [/tex]
substitute the values in the formula
[tex] P= 2*210+2*45 [/tex]
[tex] P= 420+90 [/tex]
[tex] P= 510 \ cm [/tex]
therefore
the answer is
The perimeter is equal to [tex] 510 \ cm [/tex]
The perimeter of 2m 10cm by 45cm is 510cm.
Given that,
- We assume the length be 2m 10 cm = 200 + 10 = 210cm.
- And, the width be 45cm.
- We need to find out the perimeter.
Based on the above information, the calculation is as follows:
We know that
Perimeter = 2(Length + width)
= 2(210 + 45)
= 420 + 90
= 510 cm
Therefore we can conclude that the perimeter of 2m 10cm by 45cm is 510cm.
