The area of one rectangle is equal to the square of another rectangle. The length of the first rectangle is 18 cm and the width is 15 cm. Increases the width of the second rectangle if the length of it is 27 cm?
S = A * B, where S is a rectangle area, A is a rectangle width, B – the length of the rectangle.
We will find the area of the first rectangle, for this we will find the product of the length and width of the rectangle:
S = 15 * 18 = 270 (cm ^ 2). It is known that the area of the first rectangle is equal to the area of the second rectangle. We find the width of the second rectangle, if the area of the rectangle and its length is known:
a = s: b;
a = 270: 27 = 10 (cm) – the width of the rectangle.
Answer: 10 centimeters Rectangle width.
