Answer:
Step-by-step explanation:All other quantities of physical objects can be expressed as combinations of these fundamental quantities. For example, density is volume per mass. It can be expressed as a combination of the fundamental quantities mass (M) and length (L), M/(L × L × L) = M/L3. Similarly, area is a function of length, L × L = L2.
P= 2l+2w
P-2l= 2w
1/2P -l= w
Rearrange into standard form.
w= 1/2P -l
