Question

Length of the rectangle is 5 cm more than its breadth .area is 300 sq.cm. find length and breadth

Answer 1

Answer:

let breadth be bcm

and length be lcm

ATQ

l =b+5-----eqn1

area given=300 sq CM

b( b+5) =300

b*2 +5 b= of rectangle is 20 cm300

b*2+20b -15b=300

b*2+20b -15b-300=0

b(b+20) -15(b+20) =0

(b+20) (b-15) =0

b=-20 , b=15

not possible

Step-by-step explanation:

when b= 15

then l= b+5

l =15+5

l=20cm

hence length of rectangle is 20 cm
