Step-by-step explanation:
The complete question is
Alex is planning to surround his pool ABCD with a single line of tiles. How many units of tile will he need to surround his pool?
A coordinate plane with quadrilateral ABCD at A 0 comma 2, B 3 comma 5, C 7 comma 1, and D 4 comma negative 2. Angles A and C are right angles, the length of segment AB is 4 and 24 hundredths units, and the length of diagonal BD is 7 and 7 hundredths units
we have
The coordinates of the pool are
A(0,2),B(3,5),C(7,1),D(4,-2)
Applying the Pythagoras Theorem
Find out the length of side AD
substitute the given values
Find the perimeter of the pool
The perimeter of a quadrilateral is equal to
substitute
