Question

The length of a rectangular plot is 4 meters more than its breadth. If the perimeter of the plot is 160 meters,find the dimensions of the plot

Answer 1

Solution :

Let the breadth of the rectangular plot be x

then length = x + 4

Area of rectangular plot = 2 ( l + b )

160 = 2 ( x + 4 + x )

160 = 2 ( 2x + 4 )

160 = 4x + 8

4x + 8 = 160

4x = 160 - 8

4x = 152

x = 152/4

x = 38

Hence length of rectangular plot = x + 4

= 38 + 4

= 42 cm

and length of rectangular plot = x = 38 cm .

Answer 2

Answer:

Step-by-step explanation:

given

length=breadth+4

perimeter=160

perimeter of a rectangle=2(l+b)=160

l+b=80

b+4+b=80

2b=80-4=76

b=38

now l=b+4

so

l=38+4=42
