Question

Find the breadth of the rectangle whose length is 12 cm and length of the diagonal is 15 cm.
​

Answer 1

Answer:

breadth is 9

Step-by-step explanation:

the diagonal,lenghth and breadth will form a right angled triangle

so lenghth²+breadth²=diagonal²

this is by using pythagoras theorem

b²+12²=15²

b²=225-144 ..........as 15²=225,12²=144

b²=81

b²=9²

b=9
