Question

find the lenghth and breasth from the given information

Answer 1

Answer:

length=10 and breadth=5

Step-by-step explanation:

Lengths are=x+7 and y+8

Breadths are=x+y and 3x-2y

length,

=>x+7=y+8

=>x-y=1      =>x=1+y .....(a)

breadth,

x+y=3x-2y

=>2x-3y=0 .......(b)

by putting a in b,

2(1+y)-3y=0

2+2y-3y=0

2-y=0

=>y=2  ........(c)

now, by putting c in a ,

x=1+2

=>x=3

so,

Lengths,

x+7=3+7=10

y+8=2+8=10

breadths,

x+y=2+3=5

3x-2y=3*3-2*2=9-4=5
