Question

The length of a rectangle is twice as its width, The perimeter of the rectangle is 36cm. Calculate the area of the rectangle.

Answer 1

Answer:

72cm

Step-by-step explanation:

Solution

Area = l*b

Let's assume that the width of the rectangle is x

Then its length would be 2(x)

We know that perimeter of a rectangle is 2(sum of length and width)

Substituting the values we get,

2(x+2x)=2(3x)=6x

But the perimeter is 36

Hence 6x=36

x=36/6=6

As its width is x(=6) and length 2x(=12)

Its area which is length times width is 12*6=72 cm
