Question

find the length of a rectangle with breadth 8.5 centimetre and perimeter 32 centimeter ​

Answer 1

Answer:

The length of rectangle is 7.5 cm

Step-by-step explanation:

Perimeter of rectangle = 2(L+B)

• 32 = 2(L+B)
• 32 = 2(L+8.5)cm

Now,Transposing 2

So, 32/2 = 16

• 16 = L+8.5cm

For finding length, transpose L to 16

So,

• L = 16 - 8.5cm
• L = 7.5 cm

Hence, the length of rectangle is 7.5 cm.
