Answer 1

Step-by-step explanation:

2{4X}=36

4X =18

X =9/2 ANSWER.

31X +23X =216

54X =216

X =4 ANSWER...

Answer 2

Answer:

Let the length and breadth of a rectangle be x,y respectively

Given Ratio of length and breadth of the rectangle is 3:1

⟹x:y=3:1⟹ X/y= 3/1⟹x=3y

Perimeter of a rectangle is 36 cm

⟹2(x+y)=36

⟹3y+y=18⟹y= 18/4=4.5

⟹x=3y=3×4.5=13.5

The length and breadth of a rectangle is 4.5 cm,13.5 cm respectively
