Question

Find the area of a rectangular field in hectares whose sides are:
) 35 m and 42 m
(i) 50cm and 1m
​

Answer 1

Answer:

1) .147 hectares

2).00005 hectares

Step-by-step explanation:

1) .147 hectares

2).00005 hectares

Answer 2

Answer (i) :-

Length of rectangle, l = 35 m

Breadth of rectangle, b = 42 m

We know,

$\boxed{ \bf \: Area\:of\:Rectangle=Length × Breadth}$

$\tt \: :\implies \: Area_{(rectangle)} \: = 35 \times 42$

$\tt \: :\implies \: Area_{(rectangle)} = 1470 \: {m}^{2}$

$\tt \: :\implies \: Area_{(rectangle)} = \dfrac{1470}{10000}$

$\pink{\because \: \{ { \bf \: 1 \: hectare = 10000 {m}^{2} } \}}$

$\tt \: :\implies \: Area_{(rectangle)} = 0.147 \: hectares$

Answer (ii) :-

Length of rectangle, l = 1 m

Breadth of rectangle, b = 50 cm = 0.5 m

We know,

$\boxed{ \bf \: Area\:of\:Rectangle=Length × Breadth}$

$\tt \: :\implies \: Area_{(rectangle)} = 1 \times 0.5$

$\tt \: :\implies \: Area_{(rectangle)} = 0.5 \: {m}^{2}$

$\tt \: :\implies \: Area_{(rectangle)} = \dfrac{0.5}{10000}$

$\tt \: :\implies \: Area_{(rectangle)} = 0.00005 \: hectares$

Additional Information :-

• 1 km = 10 hm = 100 dam = 1000 m
• 1 kg = 10 hg = 100 dag = 1000 g
• 1m = 10 dm = 100 cm = 1000 mm
• 1 g = 10 dg = 100 cg = 1000 mg
• 1 dm = 10 cm = 100 mm
• 1 dg = 10 cg = 100 mg
• 1 cm = 10 mm
• 1 cg = 10 mg
