Question

in a given rectangle,two times the length is 25 unitsmore than its breadth.Also,the sum of its length and breadth is 35 units.express these equations as linear equation in two variables and find the length and breadth of rectangle​

Answer 1

Let, length and breadth be x and y respectively.

the equations are,

(1) + (2)

2x-y-25 = 0

x+y-35 = 0

3x- 60 = 0

3x= 60

x=60/3

x= 20

sub x=20 in (2),

20+ y-35 = 0

y- 15 =0

y = 15

ANSWER :

Length = 20 units &

breadth = 15 units
