Given the figure, find its
- perimeter,
- area.
(a)
Perimeter of the figure
= 2 x (56 + (5 x 13) + 13 + 52)
= 2 x (56 + 65 + 13 + 52)
= 2 x 186
= 372 cm
(b)
Area of the figure
= (2 x 56 x 13) + (2 x 4 x 13) + (17 x 13)
= (2 x 728) + (2 x 52) + 221
= 1456 + 104 + 221
= 1781 cm
2 Answer(s): (a) 372 cm; (b) 1781 cm
