Answer:
Lenght: 21 inches.
Width: 14 inches.
Step-by-step explanation:
1. You know that the width (W) of a rectangle is 7 inches less than the length (L), then:
![W=L-7](https://tex.z-dn.net/?f=W%3DL-7)
2. The perimeter is 70 inches.
3. The formula for calculate the perimeter of a rectangle is:
![P=2L+2W](https://tex.z-dn.net/?f=P%3D2L%2B2W)
3. Substitute
and the value of the perimeter into the equation to calculate the perimeter and solve for the length:
![70=2L+2(L-7)](https://tex.z-dn.net/?f=70%3D2L%2B2%28L-7%29)
![70=2L+2(L-7)\\84=4L\\L=21](https://tex.z-dn.net/?f=70%3D2L%2B2%28L-7%29%5C%5C84%3D4L%5C%5CL%3D21)
4. Then the width is:
![W=L-7=21-7=14](https://tex.z-dn.net/?f=W%3DL-7%3D21-7%3D14)
