[tex]1). \: lp = (20 \times 20) + (4 \times ( \frac{1}{2} \times 20 \times 8)) \\ lp = 400 + (4 \times 80) \\ lp = 400 + 320 \\ lp= 720 {cm}^{2} \\ \\ [/tex]
[tex]2). \: lp = (24 \times 24) + (4 \times ( \frac{1}{2} \times 24 \times 10)) \\ lp = 576 + (4 \times 120) \\ lp = 576 + 480 \\ lp= 1.056 {cm}^{2} \\ \\ [/tex]
[tex]3). \: c = \sqrt{ {12}^{2} + {16}^{2} } \\ c = \sqrt{144 + 256} \\ c = \sqrt{400} = 20cm \\ \\ lp = (24 \times 24) + (4 \times ( \frac{1}{2} \times 24 \times 20)) \\ lp = 576 + (4 \times (240)) \\ lp = 576 + 960 \\ lp = 1.536 {cm}^{2} [/tex]
