length of the rectangle=25

breadth of the rectangle=20

Answer 2

Answer:

I will give you the correct answer mark me as a brainliest

and follow me.

Step-by-step explanation:

Let the sides be 5x and 4x

Length = 5x

Breadth = 4x

then,

2×(L+B) = 90cm

Therefore, 2×(5x+4x) = 90

10x+8x = 90

18x = 90

x=90/18

x= 5

So, we get x=90 then,

Length and Breadth are:

Length = 5x = 5×5 = 25cm

Breadth = 4x = 4×5 = 20cm

therefore;

Length = 25 cm.

Breadth = 20 cm.
