The perimeter of a rectangular garden is 48 m. If the length is 6 m more than the breadth, the are area (in m $^ 2 $) of the garden is:
एक आयताकार बगीचे का परिमाप 48 मीटर है। यदि उसकी लंबाई, चौड़ाई से 6 मीटर अधिक है, तो बगीचे का क्षेत्रफल (वर्ग मीटर में) कितना होगा?
Detailed Solution & Logic
135
Let the breadth be x m.
Length = x+6 m
Perimeter = 48 m
$2(l+b)=48$
$l+b=24$
$(x+6)+x=24$
$2x=18$
$x=9$
Length $=15$ m
Area $=15\times9=135\text{ m}^2$
Answer: 135 m²
