Question

eg
2] The area of a rhombus is 990 sq
cm. If the length of one of the
diagonal is 55 cm find the length of
the other diagonal. *
​

Answer 1

Answer:

The answer will be 36 cm.

Step-by-step explanation:

Area of rhombus in terms of its diagonal is given as;

ar(rhombus) = (1/2) × diagonal1 × diagonal2

Now, its given that;

area of rhombus = 990 cm²;

one diagonal = 55 cm.

Thus, other diagonal equals;

990 = (1/2) × 55 × diagonal2

(990 × 2) / 55 = diagonal2;

18 × 2 = diagonal2;

diagonal2 = 36 cm.

That's all.
