Question

The perimeter of rectangle is 30m .If its length exceed its breath by3m then find its length

Answer 1

Let the breadth be x m and length be x+3 m

Perimeter of rectangle = 2(length + breadth)

30 = 2(x+x+3)

30÷2= 2x+3

15 = 2x +3

15 - 3 = 2x

12 = 2x

12÷2=x

6=x

Therefore, Breadth of rectangle = x m =6m

And length = x+3 = 6+3= 9m.

Answer 2

hey....

here is your answer

2 (x+x+3)=30
2x+3=15
2x=12
x=6

so....x+3 =6+3=9
it is your answer
