Question

Lenght of the room is 20ft and the width is 12ft what is the perimeter

Answer 1

64ft.

Explanation:

(20ft+20ft)+(12ft+12)= 64ft

Answer 2

P=2(a+b)

=2(20+12)

=2×32

=64 feet

Explanation:

The perimeter would equal 2l + 2w, which would lend to the equation 2(20) + 2(12), or 20 + 20 + 12 + 12 = perimeter.
