Question

the sides of rectangle are in the ratio 5:4 and its perimeter is 54 cm find its length and breadth​

Answer 1

Answer: length is 15cm and breadth is 12cm

Step-by-step explanation:

take length and breadth as 5x and 4x

2(l+b)=perimeter

2(5+4x)=54

2*9x=54

18x=54

X=54/18

X=3

length=5x= 5*X=5*3=15cm

breadth= 4x=4*X=4*3=12cm

If you want verification. here it is

2(15+12)=54

54=54

Answer 2

Answer:

l=20 ,b=16
