PLSS HELP THIS WITH THIS IT IS SURFACE AREA!! :)

412 ft(2)

Step-by-step explanation:

You have too find the area of 2 trinagles and 3 rectangles(2 with the same length and 1 with a diffrent)

(tringle)

6 x 8 = 48 divide by 2 = 24

24 + 24 = 48 (cuz there are 2 trinagles)

(rectangle 1)

14 x 8 = 112

112 + 112 = 224

(rectangle 2)

14 x 10 = 140

Add all them togther

48 + 224 + 140 = 412

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

50
