To calculate: the original dimension of rectangle.
Answer to Problem 2OE
Length = 18 cm & width = 8 cm
Explanation of Solution
Given:
Length of the rectangle increased by 10 cm
Length & width decreased by 2 cm
Area decreased by 48 cm2
Calculation:
Let width of the original rectangle be =
Let length of the original rectangle be =
Now area of the original rectangle =
Length & width increased by 2 cm
So, length of the new rectangle =
width of the new rectangle =
area of new rectangle =
area of new rectangle decreased by 48 cm2
now subtracting original area from new area
So, width of the original rectangle is 8 cm
Length of the original rectangle
