Question

the perimeter of a rectangle is 64cm . if it's length is 17cm , what is it's breadth ?​

Answer 1

Answer:

breadth= 15cm

Step-by-step explanation:

Perimeter of Rectangle is =2(l+b)

here perimeter is given as 64 and length l=17cm

so,

2(l+b)=64

l+b=64/2=32

for l=17,

17+b=32

b=32-17

b=15cm

Answer 2

Question:-

The perimeter of a rectangle is 64cm . if it's length is 17cm , what is it's breadth ?

Answer:-

• The breadth of rectangle is 15 cm

To find:-

• Breadth of rectangle

Solution:-

• Perimeter of rectangle = 64 cm
• Length of rectangle = 17 cm

As we know,

$\large{ \boxed{ \mathfrak{ \pink{perimeter = 2(l + b)}}}}$

Where,

• l = length of rectangle
• b = breadth of rectangle

According to question,

$\large{ \sf : \implies \: \: \: \: \: \: \: \: 2(17 + b) = 64}$

$\large{ \sf : \implies \: \: \: \: \: \: \: \: 17 + b = \frac{64}{2} }$

$\large{ \sf : \implies \: \: \: \: \: \: \: \: 17 + b = 32}$

$\large{ \sf : \implies \: \: \: \: \: \: \: \: b = 32 - 17}$

$\large{ \sf : \implies \: \: \: \: \: \: \: \: b = 15}$

Hence,

The breadth of rectangle is 15 cm
