Question

A gardener needs to cultivate a triangular plot of land. one angle of the garden is 47, and two sides adjacent to the angle are 77 feet and 76 feet. to the nearest tenth, what is the area of the plot of land?

Answer 1

A= 1/2 x a x b x sinC
= 1/2 x 77 x 76 x sin(47)
= 2139.9409

Answer 2

We know
area of triangle =
$\frac{1}{2} \times \sin(47) \times 77 \times 76$
