Question

the length of a rectangle is 16 cm if its perimetre is 50 cm find its breadth​

Answer 1

Answer:

9

Step-by-step explanation:

perimeter of rectangle is=2(l+b)

so,50=2(16+b)

50=32+2b

50-32=2b

18=2b

b=18/2

b=9answer

★★the length of a rectangle is 16 cm if its perimeter is 50 cm find its breadth★★

$\huge\underline\mathfrak\blue{✯✯Answer✯✯}$

$breadth = 9cm$

$\underline\mathfrak\orange{let's\: find\:out!!}$

$\bold\green{using\:formula}$

➪➪perimeter of rectangle= 2(l+b)

☞︎︎︎☞︎︎︎☞︎︎we have:-

• perimeter is 50 cm
• length is 16 cm
• breadth is not given

➪➪so, we have to find breadth

for finding breadth let put B

$2(length + breadth) = 50cm$

✍︎✍︎✍︎✈︎✈︎working here :- ✍︎✍︎

$= \: 2(16 + b) = 50$

$= \: 2 \times 16 + 2 \times b = 50cm$

$= \: 32 + 2b = 50cm$

$= \: 2b = 50 - 32$

$= \: 2b = 18cm$

$= \: b = \frac{18}{2}$

$= b = 9cm$

➪➪★★hence the breadth of the rectangle is 9cm.★★
