Question

find the breadth of the rectangle whose perimeter 480cm and lenth 124 cm?​

Answer 1

Answer:

breadth=116 cm

Step-by-step explanation:

perimeter of a rectangle = 2 (l+ b)

480 = 2 ( 124+ b)

480= 248 +2b

2b= 480-248

2b=232

b=232/2

b=116

therefore, Breadth= 116cm

Answer 2

$\huge{\underline{\underline{\red{\mathfrak{Answer :}}}}}$

✪ Given :

Length of rectangle(L) = 480 cm

Perimeter = 480 cm

_____________________________

✪ To Find :

Breadth of rectangle(B)

___________________________

✪ Solution :

We know that,

$\Large{\boxed{\boxed{\purple{\mathfrak{Perimeter = 2(L + B)}}}}}$

(Putting Values)

480 = 2(124 + B)

480/2 = 124 + B

240 = 124 + B

240 - 124 = B

B = 116 cm

$\large{\boxed{\green{\sf{Breadth \: (B) = 116 \: cm}}}}$

$\rule{200}{2}$

$\boxed{\begin{minipage}{7 cm} Formula of rectangle \\ \\ Perimeter = 2(L + B) \\ \\ Area = Length \times Breadth \end{minipage}}$

$\rule{200}{2}$
