Question

If the ratio of two adjacent side of rectangle is 10:15 and perimeter is 150cm find length and breadth

30 and 45
25 and 50
10 and 15​

Answer 1

Step-by-step explanation:

let x be the sides of rectangle

10x : 15x

parimeter = 2( l + b) = 150

=> 2(10 x + 15 x ) = 150

10x + 15x = 150/2

25x = 75

x = 75/25

x= 3

Length = 10×3=30

breadth = 15×3=45

i have given you the correct explain

please make me brain list it ie helpful for you now it is correct
