Answer 1

Answer:

If the ratio of two sides of a rectangle is 3:4. If its perimeter is 122 cm, then the two sides are 36.6 cm, and the remaining two sides are 48.8 cm.

Step-by-step explanation:

Given:

Perimeter of rectangle = 122 cm

If the common multiple is x

then length = 3x and breadth = 4x

Find the length of all sides of a Rectangle.

Formula:

Perimeter of rectangle = 2(length + breadth)

2(3x + 4x) = 122

2(5x) = 122

10x = 122

x = 122 ÷ 10

x = 12.2

So length = 3x = 3(12.2) = 36.6 cm

And breadth = 4x = 4(12.2) =48.8 cm
