Answer:
hello :
the perimeter is : p = 2 ( w + l )
The area is : A= w ×l w : width l : length w ?
2 ( w + l ) = 76
w ×l = 336
you have the system :
w + l = 38 ...(1)
w ×l = 336...(2)
by (1) : l = 38 - w
subst in (2) : w ( 38 - w ) =336
38w - w²= 336
w² - 38w +336 = 0
delta = b² -4ac when : a = 1 and b= -38 c = 336
delta = (-38)² -4(1)(336) = 1444 - 1344 = 100 = 10²
w1 = (38-10)/2 = 14( the shorter sides length)
w2 = (38+10)/2 = 24( refused )
The shorter side's length of the rectangle is 24 inches. This is determined by solving the system of equations derived from the area (336 square inches) and perimeter (76 inches) constraints, resulting in a quadratic equation with two possible solutions, and the shorter side being 24 inches.

36 inches to feet
Answer: 3 feet
Since there are 12 inches in a foot divide the amount of inches by 12
*3 feet is also equal to a yard
