Answer:
Aria unui paralelogram 
Step-by-step explanation:
Folosind formula:
Aria unui paralelogram = (baza x înălțimea)
= (3√2 x 2)

Aria unui paralelogram 
8) a regular dodecagon has 12 equal sides. So if one side is 9.25 cm, a formula we can use is:
P = 12*9.25, which is:
P = 111 cm
9) A rhombus has four equal sides, so a formula we can use is:
P = 4*1.75, which is:
P = 7 yd
10) A paralleogram has four sides where opposite sides are equal, so a formula we can use is:
P = 2*10.4 + 2*5.6, which is:
P = 32 m
Equation: 450 = 128 + 150 + n
work:
1st step:
128+150 = 278
2nd step:
450-278 = 172
answer: 172
3rd step (checking) :
450 = 128 + 150 + 172
450 = 278 + 172
450 = 450

Answer:
- perimeter: 16 units
- area: 15 square units
Step-by-step explanation:
The dimensions of the rectangle are 3 by 5 units, so the perimeter is ...
P = 2(W+L) = 2(3+5) = 16 . . . units
__
The area is ...
A = WL = (3)(5) = 15 . . . square units
