Question

how to find perimeter of a rectangular land in hectares​

Answer 1

Answer:

Find the area by this conversion,

1 hectare = 10,000 sq.m

After this conversion, convert the width of the land from km to m.

Later divide the area by the width.

And find the perimeter by using, 2( width + value obtained after dividing) .

Step-by-step explanation:

A 150-hectare plot of land is rectangular and is 1.2 kilometers in width. Give the perimeter of this land.

Explanation:

150 hectares is equal to 150×10,000=1,500,000 square meters.

The width of this land is 1.2 kilometers, or 1.2×1,000=1,200 meters. Divide the area by the width to get:

1,500,000÷1,200=1,250 meters

The perimeter of the land is

2(1,200+1,250)=4,900 meters, or 4,900÷1,000=4.9 kilometers.
