The width of the rectangle is 40cm, its length is 135% of the width. Find the perimeter and area of the rectangle.

Rectangle width – 40 cm

The length of the rectangle is 133% of the width of this rectangle.

First, we find the length of the rectangle.

To do this, divide the width by 100 and multiply by 135.

40: 100 * 135 = 0.4 * 135 = 54

The length of the rectangle is 54 cm

Now we find the area of the rectangle.

S = a * b

S = 54 * 40 = 2160

Rectangle area 2160 cm2

Next, we find the perimeter of the rectangle.

P = (a + b) * 2

P = (54 + 40) * 2 = 94 * 2 = 188

The perimeter of the rectangle is 188 cm
