QuestionFind the area of triangle $ABC$ given $AE=10 \mathrm{~cm}, BC=20 \mathrm{~cm}, CD=17 \mathrm{~cm}, DE=2 \mathrm{~cm}, EF=6 \mathrm{~cm}$, correct to 3 significant figures.

Studdy Solution
Calculate the area of $\triangle ABC$.
$$Area = \frac{}{2} \times20 \mathrm{~cm} \times3.61 \mathrm{~cm} =36. \mathrm{~cm}^2$$The area of $\triangle ABC$ is $36. \mathrm{~cm}^2$ correct to3 significant figures.
