Question

The area of a rectangular field whose length is twice its breath is 2450m²​

Answer 1

Step-by-step explanation:

area of rectangle=l*b

given area =2450m2

also length =twice of breath

let l be length and b be breadth

l=2b

putt in l*b

=2b*b=2450

b^2=1225

b=+-35

breth is always positive

so b=35

l=2b =70

Answer 2

Answer:

let the breadth be x

and length will be 2x

area of rectangle = length ×breadth

2450m^2= 2x×x

2450m2= 2x^2

2450/2= x^2

1225= x^2

under root of 1225= x

x= 35

length = 2x

= 2×35

=70

breadth = x

= 35
