A rectangular park has an area of 1.36×10 to the power of 8 ft to the power of 2. The length of the park is 1.6×10 to the power of 4 ft. Divide the area by the length to find the width of the park.
Responses

a. 8.5×10 to the power of 3 ft.
b. 8.5×10 to the power of 5 ft.
c. 8.5×10 to the power of 4 ft.
d. 8.5×10 to the power of 2 ft.

Answer 1

Area ÷ length = (1.36×10^8) ÷ (1.6×10^4) = (1.36/1.6)×10^(8−4) = 0.85×10^4 = 8.5×10^3 ft.
Answer: a. 8.5×10^3 ft.
