Question

Find the lateral area of the pyramid to the nearest whole number.

Answer 1

51m

Explanation:

Answer 2

`51m^2`

Explanation:

The lateral area of the square pyramid is given by;

`A_L=a√(a^2+4h^2)`

where
`a=4m,h=6m`.

We substitute the values to obtain;

`A_L=4√(4^2+4(6^2))`

`A_L=4√(160)`

`A_L=16√(10)`

`A_L=50.5964`

`A_L\approx 51m^2`
