Question

the length of a rectangle is 4 times its width if the perimeter of the rectangle is 50 find the length and breadth of the rectangle​

Answer 1

Answer:

2(4x+x) =50

Step-by-step explanation:

2(4x+x)=50

2×5x=50

10x=50

x=50/10

x=5

Breadth=5

Length=4x=4×5=20

Answer 2

Answer:

Given is l=4b and perimeter of rectangle=50cm (since u didn't mention the unit)

Therefore, Perimeter= 2(l+b)

50= 2(5b)

25=5b

b=5cm

So l=4×5= 20cm
