A sign is in the shape of a rhombus with a 60° angle and sides of 12 cm long. Find its area to the nearest tenth. Select one: a. 62.4 cm2 b. 5.2 cm2 c. 124.7 cm2 d. 10.4 cm2
The area of a rhombus can be computed from its side (s) and angle (θ) by .. A = s^2*sin(θ) For your numbers, this is .. A = (12 cm)^2*sin(60°) ≈ 124.7 cm^2
