Question

Area of a rectangular plot is 528 m², whose length is twice of it's breadth.
Forin a quadratic equation to find length and breadth of the plot.​

Answer 1

Answer:

The required equation is 2b²= 528

Step-by-step explanation:

Let the length of the rectangle be l and breadth be b

l = 2b -------(i)

Area of rectangle = lb

lb = 528 ------(ii)

By substituting equ (i) in equ (ii)

2b*b = 528

2b²= 528

Answer 2

Answer:

let the breadth of a rectangular plot be X

then the length of a rectangular plot be 2X

area of rectangular plot = 528 m sq.

length × breadth = 528 m sq.

2X × X = 528 m sq.

2X sq. = 528 m sq.

X sq. = 528 ÷ 2

X = ✓264
