Question

A right triangle is shown. the base has a side length, b, of 30cm. the height, h, is 10cm. what is the length, in centimeters, of l?

Answer 1

I am assuming that you want me to find the hypotenuse so use the Pythagorean theorem to solve:
$a^{2}$+$b^{2}$=$c^{2}$
a=10cm and b=30cm
100+900=1000
√1000=31.625
The length of I is 31.625 cm
