Find the length of a side of a rhombus whose di... - JAMB Mathematics 2021 Question

For a rhombus,

• The diagonals bisect each other at right angles.
• The diagonals divide into four congruent right-angled triangles.

Hence,  6cm splits into 3cm each and 8cm to 4cm each

Hypotenuse(hyp) = Adjacent(adj) + Opposite(opp)

hyp\(^2\) = adj\(^2\) + opp\(^2\)

hyp\(^2\) = 3\(^2\) + 4\(^2\)

hyp\(^2\) = 25

hyp = 5

Length (L) = 5cm since a rhombus is a quadrilateral with 4 equal lengths
