Answer:
7.5 inches
Explanation:
Smaller length = 4 inches
Smaller width = 3 inches
Larger length = 10 inches
Larger width = x
If both rectangles are similar, then the ratio between both lengths and both widths is the same. Therefore, the value of "x" is:
![(x)/(3)=(10)/(4)\\ x=2.5*3\\x=7.5\ in](https://img.qammunity.org/2021/formulas/mathematics/high-school/4gzxthr8voc674v3ixy0tnjrgtnk2e1ts2.png)
