Question

The length of a rectangular field is 4.5 m longer than its breath. half the breath of field is one-third its length. Find the average of its length and breadth​

Answer 1

Answer:

11.25m

Step-by-step explanation:

Given,

let the breadth of the rectangular field be X m

Therefore, the length will be (X+4.5)m

ATQ,

X/2 = 1/3(X+4.5)

or,3X. = 2(X+4.5)

or,3x-2x= 9

or, X= 9

Therefore, Breadth of the rectangular field =9m

Length of the rectangular field. = 9+4.5

= 13.5m

Average of its length and breadth = (13.5+9)/2

= 11.25m
