Answer:
A. 7.2 centimeters
Step-by-step explanation:
The length of the base is 7.2 centimeters. The area of a rectangle is length*width
The length is unknown but the area is known. To find the length, all we have to do is divide the area from the height.
The working is as follows :
Area = 90 cm²
Height = 12.5 cm
Length = ?
<em>Length</em><em> </em><em>=</em><em> </em><em>Area</em><em> </em><em>÷</em><em> </em><em>Height</em>
<em>=</em><em> </em><em>90</em><em> </em><em>÷</em><em> </em><em>12</em><em>.</em><em>5</em>
<em>=</em><em> </em><em>7.2cm</em>
Answer:
2
Step-by-step explanation:
Solve. To do so, change the division sign into a multiplication sign, and flip the second fraction:
(2/3)/(1/3) = (2/3) x (3/1)
Multiply across:
(2 * 3)/(3 * 1) = (6)/(3)
Simplify:
6/3 = 2
2 is your answer.

Area of a rectangle = L * W
200 * 100 = 20,000
= 20,000m^2
Convert that to km^2
= 0.02km^2
