Answer 1

$\large\mathcal{\red {\underline {\overline {\mid {\purple {Answer}}\mid}}}}$

If the perimeter of the rectangle is 90 cm, find its sides. Therefore the lengths of the sides are 20 cm and 25cm.

Answer 2

Answer:

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

Step-by-step explanation:

Therefore the lengths of the sides are 20 cm and 25cm.
