Question

Find the area of the rhombus with the given diagonals. d1=3.4 cm and d2=8.2 cm

Answer 1

Check the picture below.

so we really have four right-triangles with a base of 1.7 and a height of 4.1.

`\stackrel{ four~triangles }{4\left[\cfrac{1}{2}(\underset{b}{1.7})(\underset{h}{4.1}) \right] }2(1.7)(4.1)\implies \text{\LARGE 13.94}~cm^2`
