Question

The rate of lengths and breadth of three rectangles are 4x: 3x : 2x and 3y:2y:4y. If
the total perimeter of 3 rectangles is P metres, then the relationship between
x,y and p is
1)x+y=18/p
2)x+y=14/p
3)x+y=p/18
4)x+y=16/p​

Answer 1

Answer:

answer is third option

Step-by-step explanation:

firstly add all the lengths and breadths

4x+3x+2x =9x

3y+2y+4y =9y

given perimeter is p

formula of perimeter of rectangle is 2(l+b)

p= 2(l+b)

p=2(9x+9y)

p=2x9(x+y)

p=18(x+y)

p\18=x+y
