Find the length of the rectangle.

Width of rectangle = 5.5 cm

Length of the rectangle = 16.5 cm

Explanation:

Given:

Perimeter of rectangle = 44 cm

Find:

Length of the rectangle

Computation:

Assume;

Width of rectangle = w

So,

Length of the rectangle = 3w

So,

Perimeter of rectangle = 2(L + B)

2(L + B) = 44

2(3w + w) = 44

w = 5.5

So,

Width of rectangle = 5.5 cm

Length of the rectangle = 3w

Length of the rectangle = 3(5.5)

Length of the rectangle = 16.5 cm
