Question

the breadth of a rectangle is five less than one-third of the length of the rectangle . find its dimensions if the perimeter is 142cm

Answer 1

this is the answer of your question

Answer 2

Answer:

Step-by-step explanation:

Let the length be a

Width = a/3 - 5

Perimeter = 2 (a + a/3 - 5)

=> 142 = 2( 4a/3 - 5

=> 71 = 4a/3 - 5

=> 76 = 4a / 3

=> a = 76 × 3 /4

=> a = 19 × 3

=> a = 57

Length = 57 cm

Width = 57/3 - 5 = 19 - 5 = 14 cm
