Question

given length of a rectangle is 3 times it's breadth . if the perimeter is 32 .find the length and breadth

​

Answer 1

Answer:

let the breadth be x.then,

length of the rectangle=3 times the breadth

=3x (given)

perimeter of rectangle=2(l+b)

32=2(x+3x)

32=2*4x

32=8x

x=32/8

x=4

putting value,

breadth=x=4

lenghth=3x=3*4=12
