Question

The sides of a rectangle are in the ratio 4:5 If the perimeter of the rectangle is 90 cm. Find the sides of rectangle. Also find the area of rectangle.​

Answer 1

Answer:

4x+5x=90

9x=90

x=10

4x=4*10=40

5x=5*10=50

Answer 2

Answer:

In rectangle ABCD, Given, perimeter of a rectangle = 90cm. Ratio = 4:5.

So, let us consider the side as 'x' Length of rectangle (l) = 5x. Breadth of the rectangle (b) = 4x.

We know that, Perimeter of the rectangle = 2(length + breadth) 90 = 2(5x + 4x)
