Answer:
2800 cm
Step-by-step explanation:
Multiply the width times the height times the 3rd demention
2l + 2w = 132
l = 3w + 2
2(3w+2)+2w=132
6w + 4 + 2w = 132
8w + 4 = 132
8w = 128
w = 16
l = 3(16) + 2
l = 48 + 2
l = 50
2(50) + 2(16) __ 132
100 + 32 = 132
Answer:
Area of rectangle = l×b= 3 1/4 × 1 1/2
= 31/8 = 4 7/8
So firstly, square root 9a^2 and 49: 
Next, combine like terms, and your answer will be
, or the third option.
