Question

A rectangle is twice its breadth is 2 m less than its length find the length of the rectangle if the perimeter is 8 m.

Answer 1

20 cm

Step-by-step explanation:

Let the breadth of the field = x cm ∴ its length = 2x and, its perimeter = 2 x (length + breadth) = 2 x (2x + x) = 2(3x) = 6x cm Perimeter = 60 cm

60 cm = 6x cm

x = 60/6 = 10 cm

Breadth = x cm = 10 cm

Length = 2x cm = 20 cm
