Answer:
area = 160160 inches²
area = 1.6016 × 10⁵ inches²
Step-by-step explanation:
The length of the rectangular computer chip is 22 × 10 cm and the width is 7 × 104 cm .
The area of the rectangular computer chip is the product of the length and the width.
area = length × width
area = (22 × 10) × (7 × 104)
area = 220 × 728
area = 160160 inches²
In scientific notation
area = 1.6016 × 10⁵ inches²
160160 is written as 1.6016 × 10⁵ because 1.60160 × 100000 = 1.6016 × 10⁵
Y+8=3y
-2y=-8
y=4
104*2=208
360-208=152
152/2=76
x=76°
