The two rectangles have the same area. the length of the first is 4 cm, and the width is 3 cm, what is the length of the second rectangle if its width is 5 cm greater than the width of the first rectangle.
Since from the condition of the problem the areas of both rectangles are equal, to solve the problem, you need to know the area of the first one.
1. Let’s calculate what the width of the second rectangle is equal to.
3 + 5 = 8 centimeters.
2. Let’s define the area of the first one.
3 * 4 = 12 cm².
3. Find the length of the second.
12/8 = 1.5 centimeters.
