Let the Length be x
Let and Breadth also be x
According to the question Length is 3 times of Breadth.
So the Length = x+3
Perimeter is 34 cm
So Perimeter of Rectangle = 2(L+B)
34 cm = 2(x+3 + x)
34 cm = 4x+6
34cm–6cm = 4x
x = 7cm
So now we know the value of x
we have to put 7 cm in place of x.
Length = x+3 = 7+3 cm = 10cm
Breadth = x = 7cm
Answer:
let breadth be x
then length is x+3
perimeter of the rectangle is 34 cm
2(l+b)= 34 cm
2(x+3+x) = 34 cm
2(2x+3) = 34 cm
4x+6= 34 cm
4x= 34-6
4x= 28 cm
x= 28/4= 7cm
breadth= 7cm
length= 7+3= 10 cm
