Question

The length of a rectangle is 5 cm more than its breath if the length is a decreased by 3 cm and Breadth is decreased by 2 cm then the area of the new rectangle is the same as the area of the original rectangle find the dimensions of the original rectangle

Answer 1

Answer:

let the breadth be x then length is x+5

area of the rectangle x×x+5

length 8s decreased by 3 cm then the length is x+2 and breadth is x-2

given that x×x+5=x+2×x-2

x^2+5x=x^2-4

Step-by-step explanation:

therefore 5x=-4

x=-4/5and length is 29/5

note: we need not to consider then signs since they are dimensions
