What is the perimeter of the object (Hint: Not all numbers should be used to find your answer) (Provide number only in your answer) *

27 IN

Step-by-step explanation:

If you want to calculate the perimeter of an irregular trapezoid, there's no special formula - just add all four sides:

Trapezoid perimeter = a + b + c + d

Maybe you've noticed, but it's the formula for any quadrilateral perimeter.

There's also an option that that presents itself with certain special trapezoids - like an isosceles trapezoid, where you need a, b, and c sides. Another example is a right trapezoid, where the length of the bases and one leg are enough to find the shape's perimeter (the last leg is calculated using Pythagoras' Theorem).

step-by-step explanation:

why? because i noticed a pattern. 60 120. those numbers without the zero, make the 6 times tables leaving your answer to be b since 6 times 4 is 24 and adding a zero making it 240.
