Question

PLZ HELPPPPP ME I DUNNO ‍♀️

Answer 1

P = 18 ft

A = 20 1/4 ft^2

Explanation:

Since only 1 side is given, we have to assume that the figure is a square

s = 4 1/2

Changing to an improper fraction

s = (2*4+1)/2 = 9/2

Perimeter of a square is given by

P = 4s

P = 4(9/2 ) = 18 ft

Area of a square is given by

A = s^2

= (9/2) ^2 = 81/4

Changing this back to a mixed number

20 1/4 ft^2
