Question

Please give me the right answer..I have attached the photo​

Answer 1

Step-by-step explanation:

BE = 18m - 13m = 5m

${h}^{2} + {5m}^{2} = 13 {m}^{2} \\ = > {h}^{2} = 169 {m}^{2} - 25 {m}^{2} \\ = > {h}^{2} = 144 {m}^{2} \\ h = \sqrt{144 {m}^{2} } \\ = 12m$

Area of Quadrilateral

$\frac{1}{2} (18m + 13m) \times 12m \\ = \frac{1}{2} \times 31m \times 12m \\ = \frac{1}{2} \times 174 {m}^{2} \\ = 87 {m}^{2}$
