The length of a rectangle is 15 feet. The width is 6 feet. What is the perimeter of the
rectangle?

we know that, the opposite sides of a rectangle are equal so u can simply 2 times the sum ogf length and breadth..

in your question,

length(l)=15 ft

breadth(b)=6 ft

therefore,

perimeter(p)=2(l+b)

=2(15+6)

=2×21

=42 ft

hope this helps!!!

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
