The perimeter of a rectangle is 12 cm and its width is 3/4 cm. Find its length.​

Answer 1

Answer:

To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.

Answer 2

Answer:

Area of rectangle= 2(l+b)

2(l+b)= 12Cm

2(l+3/4) = 12cm

(l+3/4) = 24

L= 24×4/3

L= 32

So length of rectangle is = 32cm Ans
