Answer :

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.
