Question

What is the length of diagonal which measures 15cm and 12cm

Answer 1

Answer:

Given that,

Digonal of a rectangle is 15cm

Width =12cm

We know that,

d= w to the power of 2+l to the power of 2

l= d 2 −w 2

d= 15 Square +12 Square

l= 15 square −12 Square

= Square root 225−144

=Square root 81 =9

Then,

We get the length of the rectangle is 9cm.
