Question

length of a rectangle is 20 more then 3 times of it breadth if perimeter of rectangle is 60m then find a linear equation this ​

Answer 1

Answer:

60 = 2 x 4b

Step-by-step explanation:

breadth = b

length = l = 3b

perimeter of rectangle = 2x(l+b)

60 = 2 x (3b+b)

60 = 2 x 4b

Further simplification (which may not be needed) :

60/2 = 4b

30 = 4b

b = 30/4
