Which is longer a perimeter of a square whose side is 7 meter or a rectangle which is 7 by 3 meter? By how many times
Longer?

Sagot :

Perimeter of a square:
Given: s = 7
P= 4s
  = 4(7)
P= 28

Perimeter of a rectangle:
Given: l = 7 w=3
P= 2(l+w)
  = 2(7+3)
  = 2(10)
P= 20

Psquare - Prectangle 
   28      -       20          = 8 meters

Therefore the perimeter of square is longer than the perimeter of the rectangle by 8 meters. :)

Length(square)=7 m

P=4s
P=4(7 m)
P=28 m

Length(rectangle)=7 m
Width(rectangle)=3 m
P=2(l+w)
P=2(7+3)
P=2(10)
P=20 m

Therefore, the perimeter of the square is bigger than the perimeter of the rectangle, but only if that's the measurement. The perimeter of the square is 7 more than the perimeter of the rectangle.

Hope this helps =)
