Question

The perimeter of a rectangular field is 120 m. If the field is 10 m longer than its
breadth, find the length and the breadth of the field.​

Answer 1

perimeter of rectangle= 2( l+b)

Now,

Let its breadth is to be x

then, its length is x+10

A/q,

perimeter of rectangular field =2( l+b)

120. = 2(x+ x+10)

120. =2(2x+10)

120/2. =2x+10

60-10. = 2x

50/2. = x

so,. x = 25

length=x+10=25+10=35m

breadth=25 m

Answer 2

Answer:

lets assume that

length = x + 10

breadth = x

perimeter of rectangle = 2(l+b)

120 =2(x+x+10)

120 =4x + 20

120 - 20 =4x

100 = 4x,25 = x

so,

length = 35

breadth = 25
