Question

a rectangular field is 100m by 80m find the ratio of: (i) length to its breadth , (ii) breadth to its perimeter "pls answer as fast as possible"

Answer 1

✰ AnSwer:

Ratio of :

• Length to its breadth = 5 : 4
• Breadth to its perimeter = 2 : 9

━━━━━━━━━━━━━━━━

✒ GiVen :

As we know that the area of rectangle

➠ l × b

➠ 100 × 80

So, it is clear from the given information that,

• Length = 100 m
• Breadth = 80 m

✒ To Find :

Ratio of :

• length to breadth
• breadth to perimeter

✒ SoluTion :

Let us find the ratio's respectively,

━━━━━━━━━━━━

(I) Length to breadth :

➥l / b

➥100 / 80

➥5 / 4

• Ratio = 5 : 4

━━━━━━━━━━━━

Now, let us find the perimeter, ➠Perimeter = 2 ( l + b )

➠Perimeter = 2 ( 100 + 80 )

➠Perimeter = 2 ( 180 )

➠Perimeter = 360

━━━━━━━━━━━━

(II) Breadth to perimeter :

➥ b / p

➥ 80 / 360

➥ 2 / 9

• Ratio = 2 : 9

☯ Hence Solved!!

━━━━━━━━━━━━━━━

Answer 2

GIVEN :

• A rectangular field is 100 m by 80 m.

• Length = 100 m

• Breadth = 80 m

TO FIND :

• (i) length to its breadth

• (ii) breadth to its perimeter

DIAGRAM :

$\setlength{\unitlength}{1.5cm}\begin{picture}(8,2)\linethickness{0.4mm}\put(7.4,2){\sf{\large{80m}}}\put(9.3,0.7){\sf{\large{100m}}}\put(8,1){\line(1,0){3}}\put(8,1){\line(0,2){2}}\put(11,1){\line(0,3){2}}\put(8,3){\line(3,0){3}}\end{picture}$

⠀

SOLUTION :

1) Length to it's Breadth :-

➨ length/breadth

➨ 100/80

➨ 5/4

∴ Ratio of length to it's breadth is 5:4.

★ Perimeter = 2 (l + b)

➨ Perimeter = 2 (100 + 80)

➨ Perimeter = 2 (180)

➨ Perimeter = 360 m

2) Breadth to it's perimeter :-

➨ Breadth/Perimeter

➨ 80/360

➨ 2/9

∴ Ratio of breadth to it's perimeter is 2:9.
