To calculate: the original dimension of rectangle.
Answer to Problem 1OE
Length = 11 cm & width = 6 cm
Explanation of Solution
Given:
Length of the rectangle increased by 5 cm
Length & width increased by 3cm
Area increased by 60 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 3 cm
So, length of the new rectangle =
length of the new rectangle =
area of new rectangle =
area of new rectangle increased by 60 cm2
now subtracting original area from new area
So, width of the original rectangle is 6 cm
Length of the original rectangle
