Question

perimeter of a rectangle is 154 its length is 2 metre more than twice is its breadth what are the length and breadth​

Answer 1

Given :- The perimeter of a rectangle is 154 metres .Length is 2 m more than twice its breadth .

To Find :- Length and Breadth of rectangle.

Answer :- Length of rectangle is 52 m and Breadth of rectangle is 25 m.

Step-by-step explanation:

• Let the Breadth be x m.

• Then, it's Length will be 2x + 2 m.

★ According to Question :-

→ Perimeter of rectangle = 2(Length + Breadth

→ 154 = 2(2x + x + 2)

→ 154 = 2(3x + 2)

→ 154 = 6x + 4

→ 154 - 4 = 6x

→ 150 = 6x

→ x = 150/6

→ x = 25 m

Therefore,

• Length of rectangle = 2x + 2 = 52 m
• Breadth of rectangle = x = 25 m

Extra shots :-

• Volume of cylinder = πr²h
• T.S.A of cylinder = 2πrh + 2πr²
• Volume of cone = ⅓ πr²h
• C.S.A of cone = πrl
• T.S.A of cone = πrl + πr²
• Volume of cuboid = l × b × h
• C.S.A of cuboid = 2(l + b)h
• T.S.A of cuboid = 2(lb + bh + lh)
• C.S.A of cube = 4a²
• T.S.A of cube = 6a²
• Volume of cube = a³
• Volume of sphere = 4/3πr³
• Surface area of sphere = 4πr²
• Volume of hemisphere = ⅔ πr³
• C.S.A of hemisphere = 2πr²
• T.S.A of hemisphere = 3πr²

Answer 2

Given :-

• Perimeter = 154 m

Let the breath be x m

∴ Length be 2x + 2 m

To Find :-

• Length
• Breadth

Solution :-

Formula of Perimeter :-

• P = 2 ( l + b)

Where

• l = length
• b = breath
• P = Perimeter

So, let's substitute the values

⟹ 154 = 2( x + 2x + 2)

⟹ 154 = 2 ( 3x + 2)

⟹ 154 = 6x + 4

⟹ 154 - 4 = 6x

⟹ 150 = 6x

⟹ 6x = 150

⟹ x = 150/6

⟹ x = 25

Thus, we got the value of x i.e 25

Now, we will be substituting these value in the length & Breadth

• Breadth = x = 25 m
• Length = 2x + 2 = 25 × 2 + 2 = 50 + 2 = 52 m

Thus, we got breadth as 25 m & length as 52 m
