A rectangle has an area of 90 square centimeters and a height of 12.5 centimeters. What is the length of the base?
A.
7.2 centimeters
B.
72 centimeters
C.
112.5 centimeters
D.
1125 centimeters
my awnser is c
No.
area = base * height
so, base = area/height
To find the length of the base of the rectangle, we can use the formula for the area of a rectangle:
Area = Length x Width
Given that the area is 90 square centimeters and the height (which is also the width) is 12.5 centimeters, we can substitute these values into the formula:
90 = Length x 12.5
To solve for the length, divide both sides of the equation by 12.5:
Length = 90 / 12.5
Calculating this, we get:
Length = 7.2 centimeters
Therefore, the correct answer is A. 7.2 centimeters.
To find the length of the base of the rectangle, we can use the formula for finding the area of a rectangle, which is:
Area = Length x Width
Given that the area of the rectangle is 90 square centimeters and the height is 12.5 centimeters, we can substitute these values into the formula:
90 = Length x 12.5
To find the length, we need to isolate the variable "Length". Divide both sides of the equation by 12.5:
Length = 90 / 12.5
Calculating this, we get:
Length = 7.2 centimeters
Therefore, Option A, 7.2 centimeters, is the correct answer.
