Question

The length of rectangle is twice its breadth and its areas is 288 cm^2​​​​​​​ . Find the dimension of the rectangle.

Answer 1

area of rectangle=l×b
let length=x
so (x)×(2x)=288 cm^2
2x^2=288 cm^2
x^2=288cm^2÷2
x=√144
x=12 cm=length
breadth=12×2=24 cm

Answer 2

☆ SoluTion =》

Answer:-

Breadth = 12cm

Length = 24cm

Given=》

Length of the rectangle is twice its breadth

Area = 288cm²

To Find =》

Dimensions of rectangle =?

Explanation =》

Let Breadth = x

then

Length = 2x

According to question

Area = 288

l×b=288

2x×x=288

2x²=288

x²=288/2

x²= 144

x= +_12

So, Breadth = 12cm

length = 2×12=24cm
