Let the sides of rectangle be 5x and 3x
Area of rectangle = 29.4 cm2
lxb=29.4
5x X 3x =29.4
15x= 29.4
X=20.4 /15
X=1.96
5x=5x1.96=9.8cm
3x=3x1.96=5.88cm

Answer:15cm
Step-by-step explanation:लांबी = 5x
ब्रेड = 3x
परिमिती =
80 सेमी 2 (एल + बी) = 80
5x + 3x = 40
8x = 40
x = 5
लांबी = 5x = 5 × 5 = 25 सेमी
ब्रेड = 3x = 3 × 5 = 15 सेमी
