The rectangle has a perimeter of 70 cm and is 15 cm

The rectangle has a perimeter of 70 cm and is 15 cm longer than its width. Find the length and width of the rectangle and the perimeter of the rectangle.

Find how many centimeters are the sum of the length and width of the rectangle.

Divide the known perimeter by 2.

Will be:

70/2 = 35 cm.

Determine the value of the sum of the length and width without taking into account the difference.

We subtract the specified difference from 35 centimeters, namely 15 cm.

Will be:

35 – 15 = 20 cm.

So the width is:

20/2 = 10 cm.

Thus, the length of the rectangle will be:

10 + 15 = 25 cm.

The area of the figure will be equal to the product of the sides.

25 * 10 = 250 cm2

Answer:

Length 25 cm, width 10 cm, area 250 cm2
