Answer 1

Answer:

hey here is ur answer of Q.25 in above pics

Q.22 is here in msg

pls mark it as brainliest

so here we go

Step-by-step explanation:

1.

let length and breadth of rectangle be l and b respectively

so according to first criteria

l=2b+1 (1)

according to second criteria

lb=528 (2)

substitute value of l from (1) in (2)

we get

2b square+b=528

ie 2b square+b-528=0

so comparing with ab square+ab+c=0

we get a=2,,b=1,,c=-528

so use delta=b square-4ac

so substitute a b and c values in it we get

delta=4225

so now use formula method we get

-b+ minus under root of 4225 /2a

we get b=-1+65/4 or b=-1-65/4

ie b=16 or b=-33/2

but are dimensions,lengths of any geometric figure negative ?

nope

so b=-33/2 is absurd

hence b=16

substitute it in (1)

we get l=(2×16)+1

so l=33

hence length of rectangular park is 33 m and breadth is 16 m
