Question

I tried it repeatedly , got it wrong .. pls help ..​

Answer 1

Length = 2x-y+13 = x -2y + 20

x+y=7 × 2

2x+2y = 14 ------> 1

Breadth =2x+6 = 3y

2x-3y = -6 ----------->2

Subtracting 2 from 1

5y = 20

y = 4

Substituting y in 1

2x+8 =14

2x=6

x=3

Length = 2×3-4+13

=6-4+13

=15

Breadth =

3 × 4 = 12

Area = 15 × 12 = 180

Perimeter = 2(12+15)

= 2×27

=54

Answer 2

Answer:

in rectangle opposite sides are equal

solve 2x-y+13 and x-2y+20

x=-2 and y= -9

Step-by-step explanation:

perimeter=2(l+b)=18

area =l*b=972
