Question

the length and breadth of a rectangle is in the ratio of 3:2. perimeter of rectangle is=280square . find length and breadth?​

Answer 1

Answer:

Length = 3x, Breadth = 2x

Perimeter of a rectangle = 2 (L + B)

100 = 2 (3x + 2x)

100 = 2 (5x)

100/2 = 5x

5x = 50

x = 10

Length = 3x = 3 × 10 = 30

Breadth = 2x = 2 × 10 = 20

Area of Rectangle = L × B

= 30 × 20

= 600 sq cm

Answer 2

Answer:

length84

breadth = 56

Step-by-step explanation:

length= 3x

breadth =2x

of rectangle =2*(length+breadth)

given :

perimeter =280

280=2(3x+2x)

280= 2(5x)

280/2 =5x

140= 5x

140/5= x

28 = x

length= 3x= 3*28 =84

breadth = 2x =2*28 = 56
