Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (51 + (5 x 15) + 15 + 45)
= 2 x (51 + 75 + 15 + 45)
= 2 x 186
= 372 cm
(b)
Area of the figure
= (2 x 51 x 15) + (2 x 6 x 15) + (21 x 15)
= (2 x 765) + (2 x 90) + 315
= 1530 + 180 + 315
= 2025 cm
2 Answer(s): (a) 372 cm; (b) 2025 cm
