Answer:
20
Step-by-step explanation:
Remember PEMDAS!
So first parentheses:
1.6^2 = 2.56
8.7 + 9.3 = 18.
Because that is inside another parentheses you multipy them.
2.56 x 18 = 46.08
Now: 46.08 divided by 1.8 = 25.6
Now subtract:
25.6 - 3.7 - 1.9 which equals 20!
Hope that helped!
Answer:
384 cm
Step-by-step explanation:
Perimeter is the sum of all external sides. (do not mix this up with area. Perimeter is the easy one) :)
There are 4 external sides.
Top = bottom = 132 cm
Left = Right = 60 cm
Add all 4 sides:
2(132) + 2(60)
264 + 120 = 384 cm
