The area of the rectangle is 36cm2, and the length of one of its sides is 9cm. Calculate the perimeter of this rectangle The length of the rectangle is 16 cm and the width is 4 times less. Calculate the area of the rectangle.

1) First you need to find the width of the specified rectangle.

To do this, we divide the known area of the figure by the specified length.

We get:

36/9 = 4 cm.

Find the perimeter of this rectangle.

To do this, multiply the sum of the length and width of the figure by 2 equal parts.

Will be:

2 * (9 + 4) = 2 * 13 = 26 cm.

Answer: 26 cm.

2) Find the width of the rectangle.

We divide the known length by the specified difference.

16/4 = 4 cm.

Determine the area of the rectangle.

We multiply the length of the shape by its width.

16 * 4 = 64 cm2

Answer: 64 cm2
