Question

Find lateral area of square pyramid

Answer 1

Answer: 352 m²

Step-by-step explanation:

You need to use this formula to calculate the lateral area of the square pyramid:

$LA=\frac{1}{2}pl$

Where "p" is the perimeter of the base and "l" is the slant height.

You need to calculate the perimeter of the square base with this formula:

$P=4s$

Where "s" is the lenght of any side of the square.

Then, this is:

$p=4(8m)=32m$

Substitute the slant height ($l=22m$) and the perimeter into the formula  $LA=\frac{1}{2}pl$. Then you get:

 $LA=\frac{1}{2}(32m)(22m)=352m^2$

Answer 2

Answer:

The lateral area of pyramid = 352 m²

Step-by-step explanation:

Points to remember

Lateral area of square pyramid = 2bh

Where b - Base of pyramid and

h - Slant height of pyramid

From the figure we can see a square pyramid

To find the lateral area of pyramid

Here b = 8 m and h = 22 m

Area = 2bh = 2 * 8 * 22

 = 352 m²

Therefore the lateral area of pyramid = 352 m²
