Question

the length of rectangular ground is 18m longer than its breadth and its perimeter is 124 find its length and breadth​

Answer 1

Answer: length is 22m and breadth is 40m.

Step-by-step explanation:

breadth = b

length = 18+b

so

perimeter of rectangle = 2(l+b)

124 = 2(18+b+b)

or, 124 = 36 + 4b

or, 124-36 = 4b

or, b =  88/4 = 22m

so

l = 18 + b

 = 18+22

 = 40m
