Write a simplified expression that represents the perimeter of an irregular quadrilateral with side lengths (2 1/4t−5), (4t+3), (1/2t−1), and (3t+2).

7 7/4 t - 1

Step-by-step explanation:

The perimeter of the quadrilateral is the sum of all the sides combined together

Given the length of the sides as (2 1/4t−5), (4t+3), (1/2t−1), and (3t+2),

Taking the sum;

Perimeter = (2 1/4t−5)+(4t+3)+(1/2t−1)+(3t+2)

Perimeter = 9/4 t - 5 + 4t + 3 + 1/2 t - 1 + 3t + 2

Collect like terms;

Perimeter = 9/4 t + 1/2 t + 4t + 3t -5 + 3-1 + 2

Perimeter = (9t-2t)/4 + 7t -1

Perimeter = 7/4 t + 7t - 1

Perimeter = 7 7/4 t - 1

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
