Question

the length of a rectangle is 5 m greater than its breadth and its perimeter is 250 m.find its length and breadth.​

Answer 1

Answer:

length=b+5

breadth=b

perimeter=250

2(b+b+5)=250

2b+5=125

2b=125-5=120

b=120/2=60

length=60+5=65

Answer 2

Answer:

length = 25 ,breadth = 20

Step-by-step explanation:

let it's breadth be X

let it's length be y

y = X+5 (1)

perimeter = 2(X+y)

= 2x + 2y =250 (2)

multiplying first eq by 2 gives us

2y - 2x =10 (3)

adding 1 and 2 gives us

4y = 260

y=260÷4 = 25

X = y-5

25-5 = 20
