Question

A rectangular piece of land measures 4.5 km long and 2.5 km wide

Answer 1

The ratio of its width to its length is; 5 :9.

The ratio of its length to its perimeter is; 9: 28.

What is the ratio of its width to its length?

1). From the task content, the land measures 4.5 km long and 2.5 km wide. Hence, the ratios is; 2.5: 4.5.

Therefore, we have; 5: 9 by expression as whole number ratios.

2) Since the perimeter of the rectangle is; 2(2.5+4.5) = 14.

The ratio of length to perimeter expressed simply is therefore; 9: 28.
