Question

The adjacent sides of a parallelogram are in the ratio 4:5. Find their lengths if the perimeter is 90 cm.

Answer 1

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) 18x = 90 x = 90/18 = 5 Length of the rectangle = 5×5 = 25cm Breadth of the rectangle = 4×5 = 20cm Here, is the diagram of rectangle Read more on Sarthaks.com
