Question

A garden has a width 13 and length 7 13 what is the perimeter

Answer 1

The correct answer is:   $16\sqrt13$ units (Option D)

Explanation:

A garden is usually rectangular in shape; therefore, you need to have the formula for the perimeter of a rectangle to find the perimeter of the garden.

The perimeter of rectangle = P = 2*(L+W) --- (A)

Where L = Length of a garden = $7\sqrt13$

W = Width of the garden = $\sqrt13$

Plug the values in equation (A) and simplify:

$P = 2*(L+W) \\ P = 2*(7\sqrt13 + \sqrt13) \\ P = 2 * (\sqrt13 * (7+1)) \\ P = 2 * (8 * \sqrt13) \\ P = 16\sqrt13$

Hence, the perimeter of the garden is $16\sqrt13$ units (Option D)
