PLEASE HELP 100 POINTS BRAINLIEST

Answer 1

Answer:

1044cm²

Step-by-step explanation:

first split the polygon into two shapes

46-21=25

so the length of a shape is 25

so 30x25=750

then 21*14=294

then 750+294=1044cm²

Answer 2

Answer:

1044 cm²

Step-by-step explanation:

Subdivide the polygon into two rectangles by drawing a vertical line from the interior vertex of the L-shape.

Area of a rectangle = width x length

⇒ area of largest rectangle (left) = (46 - 21) x 30 = 750 cm²

⇒ area of smallest rectangle (right) = 14 x 21 = 294 cm²

Total area of shape = 750 + 294 = 1044 cm²
