Answer 2

$\huge\bold{\mathtt{Question⇒}}$

A rectangular field is $15$ m long and $10$ m wide. Another rectangular field having the same perimeter has its sides in the ratio $4:1.$ Find the dimension of the rectangular field.

$\huge\bold{\mathtt{Given⇒}}$

• A rectangular field is $15$ m long and $10$ m wide.

• The other rectangular field having the same perimeter has its sides in the ratio $4:1.$

$\huge\bold{\mathtt{To\:find⇒}}$

The dimension of the other rectangular field.

$\huge\bold{\mathtt{Solution⇒}}$

Length of the field = 15 m

Width of the field = 10 m

Perimeter

= 2(Length+Width) m

= 2(15+10) m

= 2×25 m

= = $50$ m

Perimeter of both the fields are equal.

So, perimeter of the other field = 50 m

Let its length and width are 4x m and x m respectively.

According to condition,

2(4x+x) = 50

➳ 2×5x = 50

➳ 10x = 50

Divide both sides by 10.

➳ 10x÷10 = 50÷10

➳ x = 5

$\huge\bold{\mathtt{Hence⇒}}$

x = 5

Length = 4x m = (4×5) m = 20 m

Width = x m = 5 m

$\huge\bold{\mathtt{Therefore⇒}}$

The length and width of the other field are 20 m and 5 m respectively.

$\huge\bold{\mathtt{Not\:sure\:??}}$

$\huge\bold{\mathtt{Verification⇒}}$

2(4x+x) = 50

➳ 2(20+5) = 50

➳ 2×25 = 50

➳ 50 = 50

So, L.H.S = R.H.S.

Hence, verified.
