Question

find the sides of a rectangle whose perimeter is 100 cm and area is
600sq cm.
​

Answer 1

Answer:

30cm or 20cm

both L and B

Answer 2

Step-by-step explanation:

area of rectangle = l*b= 600sqcm

perimeter = 2 *( l + b) = 100

l + b =50

if l= x

then b= 50-x

area of rectangle = l*b= 600sqcm

x(50-x) = 600

50x-x^2 = 600

x^2 -50x + 600 = 0

(x-30) (x-20) =0

(x-30) = 0, (x-20) = 0

x=30, x=20

measures of length and breadth are 30 cm, 20cm
