Question

the length of a rectangle is 3 times of its width and the perimeter is 32 m find the length in easy way ​

Answer 1

Answer:

lenght

3×b

b=4

3×4=12

lenght is 12.

Step-by-step explanation:

lenght = 3 times of breath

=3×b

breath = b

perimeter = 2(l+b)

=2×3b + 2×b =32m

6b+2b=32m

8b=32m

b=32/8

b=4

Answer 2

Answer:

The length of the rectangle is 12 metres.

Step-by-step explanation:

Let, Width of Rectangle be b metres.

Then, Length of Rectangle is 3b metres.

Given, Perimeter = 2(l+b) = 32 metres

Or, 32 metres = 2(l+b) = 2(3b+b) = 2(4b) = 8b

Or, b = 32/8 = 4 metres

Length = 3b = 3x4 = 12 metres.

Hope this helps!
