Question

5. Area of a rectangle is xy. If its breadth is x, then
its length is .
6. The side of a rhombus is 3 cm. Its perimeter is cm.
​

Answer 1

Answer: According to the given condition. In first case. If the length of a rectangle is reduced by 5 units and its breadth is increased by 3 units, then the area of the rectangle is reduced by 8 square units. Area of rectangle = length × breadth. xy - 8 = (x - 5) (y + 3) x (y + 3)-5 (y + 3) = xy - 8. xy + 3x - 5y - 15 = xy - 8.
