Answer:

80 units

Explanation:

triangle abc will be isosceles right triangle. angle bae and angle bce is 45° . same with triangle bcd.

take triangle aeb. angles bae and bce are 45°

sum of angles in triangle is 180

so aeb = 180 - 90=90°

6x = 90

x = 15

side = 2x-10 = 2*15 - 10 = 20

perimeter = 80units
