The two rectangles have the same area. The length of the first rectangle is 18 cm, width is 15 cm. What is the width of the second rectangle if its length is 27 cm?
In order to find the area of a rectangle, you need to multiply the width by the length.
1) 18 * 15 = 270 (cm ^ 2) – the area of the first rectangle.
It is known that two rectangles have the same area, and the length of the second rectangle is also known, 27 cm.
Find the width of the second rectangle:
a = S / b, S is the area of the rectangle, b is the length of the rectangle, a is the width of the rectangle.
a = 270/27 = 10 (cm) – the width of the second rectangle.
Answer: the width of the second rectangle is 10 centimeters.
