Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (51 + (5 x 14) + 13 + 47)
= 2 x (51 + 70 + 13 + 47)
= 2 x 181
= 362 cm
(b)
Area of the figure
= (2 x 51 x 14) + (2 x 4 x 14) + (17 x 14)
= (2 x 714) + (2 x 56) + 238
= 1428 + 112 + 238
= 1778 cm
2 Answer(s): (a) 362 cm; (b) 1778 cm
