Answer:
Step-by-step explanation:
The equation is already solved for the variable t To solve for any other variable simply rearrange theequation to have the indicated variable on one sideof the equals sign and everything else on the other. For example, to solve for a: t=an+b subtract b from both sidest-b = an divide both sides by n(t-b)/n = a Or: a = (t-b)/n Work in the same manner to solve for either b or n: b = t-an n = (t-b)/a
Answer is 28 inches.
A square has equal sides and to find the perimeter, you add all the sides.
7 x 4 = 28
