Question

the length of a rectangular field is 8m less than twice it 'so breadth. if the perimeter of the rectangular field is 56m, find its length and breadth

Answer 1

Let the breadth be b

Length = 2b-8

Perimeter = 56cm. (Given)

Perimeter of rectangle= 2(l+b)

56= 2(2b-8+b)

56/2 = 2b+b-8

28= 3b-8

28+8= 3b

36 = 3b

b=36/3

b= 12

Breadth = 12

Length = 2x-8 = 2×12-8= 24-8= 16
