Question

1. Calculate the area of the land enclosed between eastings 79 and 83 and northings 77 and 84.
2. Calculate the area enclosed by eastings 78 and 86 and northings 84 and 90.
3.Calculate the area of the land enclosed between eastings 79 and 83 and northings 92 and 97

Answer 1

✏️QUESTION 1

• EASTINGS = 79 and 83 = 4
• NORTHINGS = 77 and 84 = 7

Area enclosed between this place

$= ( \frac{1}{2} \times 4 \times 7)km ^{2} \\ = (2 \times 7) km^{2} \\ = 14 {km}^{2}$

✏️QUESTION 2

• EASTINGS = 78 and 86 = 8
• NORTHINGS = 84 and 90 = 6

Area enclosed between this place,

$= ( \frac{1}{2} \times 8\times 6)km ^{2} \\ = (4 \times 6) km^{2} \\ = 24 {km}^{2}$

✏️QUESTION 3

• EASTINGS = 79 and 83 = 4
• NORTHINGS = 92 and 97 = 5

Area enclosed between this place,

$= ( \frac{1}{2} \times 4 \times 5)km ^{2} \\ = (2 \times 5) km^{2} \\ = 10 {km}^{2}$

☆NOTE : HERE ALL THE AREAS ARE CALCULATED IN km^2 SCALE.
