The expression 2/ +2w is used to find the perimeter of a rectangle with length / and width w what is the perimeter of a rectangle with length 15 and width 4 cm

perimeter = 2 l + 2w

here l = 15 and w = 4

perimeter = ( 2 × 15 ) + ( 2 × 4 ) = 30 + 8 = 38cm

38 cm

Step-by-step explanation:

Given : The expression 2/ +2w is used to find the perimeter of a rectangle with length / and width w .

For length 15 cm and width 4 cm, the perimeter of a rectangle will be :-

Perimeter :

Hence, the perimeter of a rectangle with length 15 cm and width 4 cm is 38 cm.
