Answer:The lateral area is ![364\ cm^{2}](https://tex.z-dn.net/?f=364%5C%20cm%5E%7B2%7D)
Step-by-step explanation:
we know that
The lateral area of the right prism is equal to
![LA=Ph](https://tex.z-dn.net/?f=LA%3DPh)
where
P is the perimeter of the base
H is the height of the prism
Find the perimeter of the base P
----> the rhombus has four equal sides
![h=13\ cm](https://tex.z-dn.net/?f=h%3D13%5C%20cm)
substitute
![LA=28(13)=364\ cm^{2}](https://tex.z-dn.net/?f=LA%3D28%2813%29%3D364%5C%20cm%5E%7B2%7D)
Answer:
12+40= 52
180-52=128
Step-by-step explanation:
Angles in a triangle add up to 180
so if two sides are given , they must be added and subtracted from 180.
which gives us 180-52=128
The least amount is the smallest amount, 1/8.
