Question

The perimeter of a rectangle is 34 units. Its width is 6.5 units.

Write an equation to determine the length (L) of the rectangle.

Answer 1

10.5 units

Explanation:

From the question;

• Perimeter of a rectangle is 34 units
• Width of the rectangle is 6.5 units

We are supposed to determine the length of the rectangle;

• We know that the perimeter of a rectangle is given by;

P = 2(L+W), where L is the length and W is the width.

Therefore, in this case;

34 units = 2(L + 6.5 units)

We get;

34 units = 2L + 13

Solving for L,

2L = 34 - 13

2L = 21

L = 10.5 units

Thus, the length, L, of a rectangle is 10.5 units
