The number of units of tiles he will need is 18.96 units
Step-by-step explanation:
The parallelogram ABCD has a right triangle ABD with A as 90°
The length of segment AB is given as 3.16 units and that of the diagonal BD is 7.07 units.
Apply Pythagorean relationship to find length of segment AD=BC
The sum of squares of the sides equals the square of the hypotenuse.
a²+b²=c²
In this case, side a=3.16 units, b=AD and c=hypotenuse=7.07
Applying the formula;
a²+b²=c²
3.16²+b²=7.07²
9.99+b²=49.99
b²=49.99-9.99
b²=40
b=√40=6.3245 =6.32
AD=BC=6.32 units
Find the perimeter of the quadrilateral
=3.16+3.16+6.32+6.32=18.96 units
