Question

the area of a rhombus is 42 sq m. If one of its diagonal is 12m ,then the other diagonal is____ m

Answer 1

this is your answer brother mark me as the brainliest

Answer 2

Answer:

Length of the other diagonal is 7m.

Explanation:

We know that,

Area of a rhombus = ½ • $d_1$ • $d_2$

Where,

• Area is 42m²
• $d_1 \sf (one \: diagonal)$ = 12m
• $d_2 = \sf (other \: diagonal)$

So,

→ 42 = ½ • 12 • $d_2$

→ 42 = 6 • $d_2$

→ 42/6 = $d_2$

→ 7 = $d_2$

Hence, the length of the other diagonal is 7m.
