Question

length of the diagonals of a parallelogram are 10 cm and 15 cm. what is it's surface area ​

Answer 1

Answer:

your question is incomplete

Step-by-step explanation:

the formula for finding the area of ||gm using diagonals is

$1 \div 2 \times pq \sin(θ)$

where p and q are the length of diagonals and sinθ is the angle between them. your question contains the length of p and q but not the angle between them. there is one more way but that is only for vectors and that is

$1 \div 4(p + q)(p - q)$

I HOPE YOU FOUND YOUR ANSWER!
