Question

The perimeter of a kite is 40 cm. What are the lengths of the other 3 sides, if the length of one of its sides is 15 cm?

Answer 1

A kite has two pairs of equal sides. Therefore, Perimeter of kite $=2(a+b)=40cm$

$\Rightarrow 2(a+15)=40cm\Rightarrow a+15=20cm\Rightarrow a=5cm$

Therefore measure of sides of kite are $20cm,20cm,5cm$ and $5cm$.
