»Question -
Half the perimeter of a rectangular garden,whose length is 4 m more than its width is 36m. Find the dimensions of garden.
» Given:
•length is 4 m more than width
• Half the perimeter = 36
» Solution
take the width as x.
then,
the length becomes - (x+4)
half the perimeter = 36
therefore, perimeter =
36×2
= 72 m
» We know that,
»by putting values
72 = 2{(x+4)+(x)}
72 = 2{x+4+x}
72 = 2(2x+4)
72 = 4x+8
4x = 72-8
4x= 64
x = 64/4
