Question

perimeter of rectangle is 40m.the length of the rectangle is the 3 times of the breadth.
find the area, length and breadth​

Answer 1

Answer:

area= 75cm*2, length=15cm,breadth=5

Step-by-step explanation:

Given- perimeter = 40m

3b = l

Now,

perimeter of rectangle = 2(l+b)

=2( 3b+b)

=2(4b)

40=8b

b=5m

Now,

length= 3 x breadth

length= 3 x 5

= 15m

Now, area of rectangle = length x breadth

= 15 x 5 =75 m*2
