Here in this problem, pqrs is a rectangle, p .s given as 7 and p are given as 25.
00:12
We have to find out the measure of pq.
00:18
Okay, now triangle p s are, that's a right angle triangle because all the angles of a rectangle is 90 degrees.
00:29
So angle s is 90 degree.
00:31
So we can write pr square, pr square is equal to p s square plus sr square.
00:42
Here, pr is the hypotenuse, the side opposite to that 90 degree angle, that is angle s, is equal to some of the square of the two legs, according to pythagorean theorem.
01:03
Now, pr square, that is 25 square, ps is 7, so p .s...
