If the length of a room is increased by 3 m and its breadth is decreased by 3m l, its area decreased by 15 m^2. if both length and breadth is decreased by 3m, its area increases by 63 m^2, by what percentage the length is more than breadth? show it by step by step calculation.

Iam a rectangle. my perimeter is 60 feet. how much are do i cover?

The length of a rectangle is x times the square root of 100. the width is one-half y more than three-halves x. given that the area of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y? a) 5xy − 15x = 125 b) 5xy + 15x = 125 c) 15x2 − 5xy = 125 d) 15x2 + 5xy = 125
