Question

half the perimeter of a rectangular garden, whose length is 4m more than its width, is 36m find the dimensions of the garden

Answer 1

a/q
l+ b = 36
(x+4) + x =36
2x = 32
x= 16
length= 20 m
breadth= 16 m

Answer 2

Let the width of the garden be x

So, the length of the garden will be 4+x

Now, the formula of perimeter of rectangle is,

P= 2(l+w)

According to the question

36=[1/2{2(4+x+x)}]

36=(4+2x)

36-4=2x

32=2x

32/2=x

16=x

Length=4+x

=4+16
