1. L = Length

The length of a rectangle is 5 cm longer than the its breadth mean:

L = B + 5

P = 2 L + 2 B

P = 2 ( L + B )

Replace L with B + 5 inn this equation

P = 2 ( B + 5 + B )

P = 2 ∙ ( 2 B + 5 )

26 = 4 B + 10

Subtract 10 to both sides

16 = 4 B

Divide both sides by 4

4 = B

B = 4 cm

L = 4 + 5

L = 9 cm

P = 2 ( L + B )

P = 2 ∙ ( 4 + 9 )

P = 2 ∙ 13

P = 26 cm
