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:
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
