Question

Part 1
A rectangle has perimeter 86cm and 36cm length . What is its​ width?

Answer 1

To find the width of a rectangle, we can use the formula for perimeter:

Perimeter = 2(length + width)

We are given that the perimeter is 86 cm and the length is 36 cm.

So, we can substitute these values into the formula:

86 = 2(36 + width)

Now, let's solve for the width:

86 = 72 + 2(width)

86 - 72 = 2(width)

14 = 2(width)

Divide both sides by 2:

7 = width

Therefore, the width of the rectangle is 7 cm.
