Question

The ratio of the length of the rectangular field to its width 5:2. The length of the field is 30yd. Find the perimeter and area

Answer 1

Perimeter= 84

Area= 360

Explanation:

We know that this field has portions split up by 7. The length is 5/7 of that, and the width is 2/7.

We know that the length is 30yd. 30/42 is the equivalent of 5/7. That means that 12/42 is the equivalent of 2/7.

Thus, the width of the field is equal to 12.

To find the perimeter we will add all sides. 30 + 30 + 12 + 12 = 84

We will multiply them to find area. 30 * 12 = 360
