Question

find then length of a diagonal of rectangle with dimension 20m by 15m

Answer 1

Answer:

Diagonal of a rectangle=√L2+B2

√20×20+15×15

√400+225

√625

25 ans.

Answer 2

Answer:

25 m

Step-by-step explanation:

if ABCD is the rectangle and AB and BC are two sides, then AC will be the diagonal.

now, rectangle has all angle 90°

so,

triangle ABC has agnle B is 90°

now using Pythagoras theorem,

we know that,

hypotenuse ² = one side² + second side²

AC² = AB² + BC²

AC² = 20² + 15²

AC² = 400 + 225

AC² = 625

AC = + 25 or - 25

but diagonal can not be negative so,

AC = Diagonal of rectangle = 25 m.

hooe this will help you.

Thank you.
