Given :⬤ Perimeter of Rectangular Field is 240 m .⬤ Length of Rectangular Field is 90 m .To Find :⬤ Breadth of Rectangular Field .⬤ Area of Rectangle .Formula Used :

$\bf[\:{Perimeter \: of \: Rectangle =2(l+b)} \: ]$

l = Length .

l = Length .b = Breadth .

l = Length .b = Breadth .Solution :

l = Length .b = Breadth .Solution :Let :

l = Length .b = Breadth .Solution :Let :Breadth of Rectangular Field be b .

l = Length .b = Breadth .Solution :Let :Breadth of Rectangular Field be b .According to the Formula :-

l = Length .b = Breadth .Solution :Let :Breadth of Rectangular Field be b .According to the Formula :-240 = 2 (l + b)

l = Length .b = Breadth .Solution :Let :Breadth of Rectangular Field be b .According to the Formula :-240 = 2 (l + b)240 = 2 (90 + b)

l = Length .b = Breadth .Solution :Let :Breadth of Rectangular Field be b .According to the Formula :-240 = 2 (l + b)240 = 2 (90 + b)240 = 180 + 2b

l = Length .b = Breadth .Solution :Let :Breadth of Rectangular Field be b .According to the Formula :-240 = 2 (l + b)240 = 2 (90 + b)240 = 180 + 2b240 - 180 = 2b

l = Length .b = Breadth .Solution :Let :Breadth of Rectangular Field be b .According to the Formula :-240 = 2 (l + b)240 = 2 (90 + b)240 = 180 + 2b240 - 180 = 2b60 = 2b

l = Length .b = Breadth .Solution :Let :Breadth of Rectangular Field be b .According to the Formula :-240 = 2 (l + b)240 = 2 (90 + b)240 = 180 + 2b240 - 180 = 2b60 = 2b60/2 = b

l = Length .b = Breadth .Solution :Let :Breadth of Rectangular Field be b .According to the Formula :-240 = 2 (l + b)240 = 2 (90 + b)240 = 180 + 2b240 - 180 = 2b60 = 2b60/2 = b30 = b

l = Length .b = Breadth .Solution :Let :Breadth of Rectangular Field be b .According to the Formula :-240 = 2 (l + b)240 = 2 (90 + b)240 = 180 + 2b240 - 180 = 2b60 = 2b60/2 = b30 = bTherefore , The Breadth of Rectangular Field is 30 m .

l = Length .b = Breadth .Solution :Let :Breadth of Rectangular Field be b .According to the Formula :-240 = 2 (l + b)240 = 2 (90 + b)240 = 180 + 2b240 - 180 = 2b60 = 2b60/2 = b30 = bTherefore , The Breadth of Rectangular Field is 30 m .Formula Used :

$\bf [\:{Area \: of \: Rectangle \: = l \times{b}}]$

$\bf{Area of Rectangle = (l \times b) }$

l = Length

l = Lengthb = Breadth

l = Lengthb = BreadthNow :

l = Lengthb = BreadthNow :Length = 90 m .

l = Lengthb = BreadthNow :Length = 90 m .Breadth = 30 m .

l = Lengthb = BreadthNow :Length = 90 m .Breadth = 30 m .According to the Formula :-

l = Lengthb = BreadthNow :Length = 90 m .Breadth = 30 m .According to the Formula :-l × b

l = Lengthb = BreadthNow :Length = 90 m .Breadth = 30 m .According to the Formula :-l × b90 × 30

l = Lengthb = BreadthNow :Length = 90 m .Breadth = 30 m .According to the Formula :-l × b90 × 302700

l = Lengthb = BreadthNow :Length = 90 m .Breadth = 30 m .According to the Formula :-l × b90 × 302700Therefore , The Area of Rectangular Field is 2700 m² .

Answer 2

Answer:

b = 30

Step-by-step explanation:

Given:

Perimeter of a rectangle is 240 m

Length is 90 m

To find:

Breadth of the rectangle

Solution:

Perimeter is 240

i.e.

2(l+b) = 240

(l+b) = 120

(90+b) = 120

b = 120 - 90 = 30
