Question

The length of a rectangle is twice its breadth and its area is 288cm?.. Find the dimensions of the rectangle.
​

Answer 1

Answer:

Length=24cm ,Breadth=12cm..

Step-by-step explanation:

Let it's breadth be x.cm

Then length=2x.cm

Area=length×breadth

=2x ×x

=2x²cm²

But,area according to question

=288cm²

2x²=288

x²=288/2

x²=144

x=√144

x=12cm

Hence,Breadth=12cm

Length=2x=2×12=24cm

Answer 2

Answer:

12×24

Step-by-step explanation:

2x×x=288cm

2x^2=288cm

x^2=288÷2

x^2=144

x=√144

x=12

so length = 2x =so 12×2 =24 cm

breadth=12 cm

so dimension of rectangle = 12×24
