OpenStudy (anonymous):

You are given the height of the triangle to be 22 and the base to be 8 cm. so simply use the formula of a triangle which is base*height/2 or 22*8/2= 88cm^2, but since there are 4 of them, just quadruplicate the 88, giving you 352cm^2.

OpenStudy (igreen):

LA = 1/2 * P * s

OpenStudy (igreen):

LA = 1/2 * 8 * 8 * 22

OpenStudy (igreen):

Simplify

OpenStudy (igreen):

P is perimeter..'s' is slant height.

OpenStudy (michele_laino):

hint: the requested lateral area is four times the area of the triangle whose base is 8 cm, and whose height is 22 cm

OpenStudy (i_love_my_nieces):

@iGreen is that 1 divided by 2 or 1 over 2

OpenStudy (i_love_my_nieces):

@Hoslos Can you show your work for me so I can write in done in my notebook for notes, please?

OpenStudy (igreen):

It's the same thing.

OpenStudy (igreen):

\(\sf LA = \dfrac{1}{2} \times 8 \times 8 \times 22\)

OpenStudy (i_love_my_nieces):

Can you please give me the formula?

OpenStudy (igreen):

\(\sf LA = \dfrac{1}{2}Ps\) Where 'P' is the perimeter(multiplying the base to the base) and 's' is the slant height.

OpenStudy (i_love_my_nieces):

Okay thank you

OpenStudy (i_love_my_nieces):

So, all I show for my work would be: 1/2 x 8 x 8 x 22 = 704 cm??

OpenStudy (i_love_my_nieces):

@iGreen am I right on how to show my work??

OpenStudy (i_love_my_nieces):

@iGreen @iGreen @iGreen @iGreen @iGreen

OpenStudy (igreen):

Correct

OpenStudy (i_love_my_nieces):

OK thank you will you help me with like one or two more please?
