Question

The Length of a rectangle is four times its breadth and the perimeter of the rectangle is 90m.find the dimensions of the rectangle.​

Answer 1

Answer:

Step-by-step explanation:

Breadth is 9 and length is 36

PERIMETER= 2(l+b)

length is four times breadth

SO l= 4b

HENCE

90= 2(4b+b)

45 = 5b

9=b

SO, Breadth is 9 and length is 36

Answer 2

Answer:

The length is 36 m and the breadth is 9 m

Step-by-step explanation:

Given: The length is four times the breadth

so let breadth be 'b' so length is '4 b'

Now perimeter 'p' = 90 m

perimeter = 2 (length+breadth)

90 = 2( 4 b + b)

90 = 8 b + 2 b

90 = 10 b

b = 90/10 = 9 m

so breadth = 9 m

and length = 4 b = 4 x 9 = 36 m
