The width of a rectangular wheat field is 850m and it is 150m less than the length, find the area of the field and express in hectares 1275 hectares 85 hectares 850 hectares.
First, we find the length of the field:
850 + 150 = 1000 (m) – field length.
The area is calculated by the formula: S = a * b, where a is the width, b is the length.
S = 1000 * 850 = 850,000 (m2).
One hectare contains 10,000 m2. In order to express the area in hectares, the area found must be divided by 10,000.
850000: 10000 = 85 (ha).
Answer: the area of the wheat field is 85 hectares.
