Question

length=84m breadth=? perimeter=328m​

Answer 1

Given :

• Length = 84 m
• Perimeter = 328 m

To Find :

• Breadth = ?

Solution :

By seeing question, we can clearly see that we are given length and perimeter of rectangle and we have to find breadth of rectangle.

To find it, we have a formula :

$\large \underline{\boxed{\bf{Perimeter_{(rectangle)} = 2(Length + Breadth)}}}$

We have :

• Length = 84 m
• Perimeter = 328 m

So, by filling values :

$\sf : \implies 328 \: m = 2(84 \: m + Breadth)$

$\sf : \implies \dfrac{328}{2} \: m = 84 \: m + Breadth$

$\sf : \implies \cancel{\dfrac{328}{2}} \: m = 84 \: m + Breadth$

$\sf : \implies 164 \: m = 84 \: m + Breadth$

$\sf : \implies 164 \: m - 84 \: m = Breadth$

$\sf : \implies 80 \: m = Breadth$

$\large \underline{\boxed{\bf{Breadth = 80 \: m}}}$

Hence, breadth of rectangle is 80 m.

Answer 2

Answer:

$\huge\underline{\mathbb\red{❥︎A}\green{N}\mathbb\blue{S}\purple{W}\mathbb\orange{E}\pink{R}}\:$

Breadth= Perimter÷Length

= 328/84= 80 m

Breath= 80 m
