Answer 1

52 ft

Explanation:

Given that:

We have an pyramid with square base.

Area of base of the square pyramid = 169
`ft^2`

To find:

Perimeter of the base of pyramid = ?

Solution:

First of all, let us have a look at the formula of area of a square shape.

`Area = Side * Side`

Let the side be equal to
`a` ft.

Putting the given values in the formula:

`169 = a^2\\\Rightarrow a =√(169)\\\Rightarrow \bold{a = 13\ ft}`

Now, let us have a look at the formula for perimeter of square.

Perimeter of a square shape = 4
`*` Side

Perimeter =
`4* 13 = \bold{52\ ft}`
