Take a look at triangle OFG, whose hypotenuse is 13 and whose longer side is 12. Its shorter side is 5, via the Pythagorean Theorem. Thus, the width of the trapezoid is 5.

Then the area of the trapezoid is

A = (average of the lengths of the trapezoid)(width of trapezoid)

30+ 40

= -------------- * 5 = 35*5= 175 square units.

The sum of the measures of the interior angles of a convex polygon is 1080° Classify the polygon by the number of sides

lozanna [386]

Answer:

(n-2)×180=1080

180n -360=1080

180n = 1080+360

180n =1440

dividing by 180

n=8

hence it is a regular polygon with 8 sides .I.e it is an octagon

Step-by-step explanation:

we are given the total interior angles in the polygon and we know that the formula to find the total interior angles of a polygon is (n-2) ×180

where n is the number of sides
