Question

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

Answer 1

The perimeter is 42 feet because 15+15+6+6 ( all the sides) adds up to the perimeter

Answer 2

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!!!
