Calculate the area of the polygons in the picture. All measurements are in cm.

Why is there a b) in the middle of the polygon?  Question creators, proofread your figures.

a) Two triangles and a kite

Top triangle (1/2)(5.53)(1.5)

Bottom triangle (1/2)(6)(2)

The kite is like two triangles with shared base 2+3=5 and combined height 7,

(1/2)(5)(7)

Adding it up,

area = (1/2)(5.53)(1.5) +  (1/2)(6)(2) + (1/2)(5)(7) = 27.6475

27.6475  sq cm

b) Three triangles, including one right triangle

Area = (1/2) (6.7)(3) + (1/2)(6.2)(2.5) + 1/2(6.2)(2) = 24.

24 sq cm

horizontal translation of 2 units in the positive x direction

vertical translation of 3 units in the positive y direction

cut 138 centimeters off

step-by-step explanation:

250-112 = 138
