PLEASE HELP ASAP!!!!!!!
maria [59]

Answer:

40 cm² = <em>B</em>

178,127514 ≈ LA

218,127514 ≈ <em>SA</em>

Step-by-step explanation:

First and foremost, since we were not given a height, to find the height, take one-third of the <em>area </em><em>base</em><em> </em>[<em>area base</em> in this case is <em>ws</em><em>,</em><em> </em>since it is a rectangular base]:\frac{1}{3}(40) = 13 \frac{1}{3}

This is your <em>height</em><em>.</em>

Now, to find the lateral area, we use this formula:

l \sqrt{(\frac{w}{2})^{2} + {h}^{2}} + w \sqrt{( \frac{l}{2})^{2} + {h}^{2}} = L. A.

Plugging these numbers into this formula will give you an approximate value of 178,127514.

Then you add the lateral area to the base area to get your surface area:

40 + 178,127514 = 218,127514

I am joyous to assist you anytime.
