The area of rectangle is xy where x is length and y is breadth .If the length of rectangle is increased by 5 units and breadth is decreased by 3 units, the new area of rectangle will be
Answers
Answer:
Step-by-step explanation:
given:
Length of rectangle is x
Breadth of rectangle is y
Length of rectangle increased 5 units
Breadth of rectangle decreased 3 units
New dimensions of rectangle:
We have given Length of rectangle is x and increased by 5 units. so the new length of rectangle = x + 5
We have given Breadth of rectangle is y and Breadth decreased by 3 units. so the new breadth of rectangle = y - 3
To finD:
Area of rectangle after increased dimensions.
Solution:
We have given Length of rectangle = x +5
Breadth of rectangle = y - 3
As we know that,
Area of rectangle = Length × Breadth
So, by this formula we can find the area of rectangle.
Substituting value in formula :
Area of rectangle = Length × Breadth
⇒ Area of rectangle = ( x + 5 ) × ( y - 3 )
⇒ Area of rectangle = x ( y - 3 )+5 ( y - 3 )
⇒ Area of rectangle = xy - 3x + 5y - 15
⇒ Area of rectangle = xy - 3x + 5y - 15
Answer:
given:
Length of rectangle is x
Breadth of rectangle is y
Length of rectangle increased 5 units
Breadth of rectangle decreased 3 units
New dimensions of rectangle:
We have given Length of rectangle is x and increased by 5 units. so the new length of rectangle = x + 5
We have given Breadth of rectangle is y and Breadth decreased by 3 units. so the new breadth of rectangle = y - 3
To finD:
Area of rectangle after increased dimensions.
Solution:
We have given Length of rectangle = x +5
Breadth of rectangle = y - 3
As we know that,
Area of rectangle = Length × Breadth
So, by this formula we can find the area of rectangle.
Substituting value in formula :
Area of rectangle = Length × Breadth
⇒ Area of rectangle = ( x + 5 ) × ( y - 3 )
⇒ Area of rectangle = x ( y - 3 )+5 ( y - 3 )
⇒ Area of rectangle = xy - 3x + 5y - 15
⇒ Area of rectangle = xy - 3x + 5y - 15
