Question

one side of a rectangular field of area 0.5 ha is 40 m. Find the other side in metres.
it's answer is 125 m i need full explanation step by step​

Answer 1

Answer:

❏ Given :

• One side of a rectangular field of area 0.5 ha is 40 m.

❏ To find :

• Find the other side in metres.

❏ Solution :

➸Given area =. 5ha

And we know that

$\mathtt\pink{1 ha =10000 {m}^{2} }$

➸So area of field will be 5000

$\frak\red{Area \: of \: rectangle \: = l \: X \: b}$

$\sf\red{5000=125 X B}$

$\sf\red{B=40}$

❏ Hence :

✔The other side is 40.

Answer 2

$\large\underline{\underline{\dag{\pmb{\sf{\pink{ \: Given :-}}}}}}$

• ➥ Side of a rectangular field is 40 m and its area is 0.5 hr.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

$\large\underline{\underline{\dag{\pmb{\sf{\pink{ \:To \: Find :-}}}}}}$

• ➥ Find the Second side of field.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

$\large\underline{\underline{\dag{\pmb{\sf{\pink{ \: Solution :-}}}}}}$

❒ We know that :

$\blue \bigstar \: \underline{ \boxed{\red{\sf {Area{\small_{(Rectangle)}} = Length \times Breadth}}}}$

➢ Here :

• ➳ Area = 0.5 he = 5000 m
• ➳ Length = x
• ➳ Breadth = 40 m

❒ Second side :

$\large{:\longmapsto\sf{Area = Length \times Breadth}}$

$\large{:\longmapsto\sf{5000 = x \times 40}}$

$\large{:\longmapsto\sf{ x = \cancel\frac{5000}{40} }}$

${\large{\blue{\longmapsto{\orange {\underline{\boxed{\sf{X = 125m}}}}}}}}$

❒ Hence :

$\large\underline{\green{\underline{\frak{\pmb{Length = Second \: side = 125m}}}}}$
