Question

Find breadth of rectangle whose length is 15m and diagonal is 17m

Answer 1

Answer:

the breadth is 8 m

Step-by-step explanation:

by Pythagoras theorem

17² = 15² + x²

17²-15² = x²

64 = x²

x= 8 m

Answer 2

Answer:

The breadth of the rectangle is 8m...

Step-by-step explanation:

Consider Rectangle ABCD . In rectangle ABCD , BD is the diagonal.

Length of Rectangle = 15m

Diagonal = 17m

Consider Triangle ABD .

We know that each angle of a rectangle measures 90 degree.

Therefore, Here Angle A = 90 degree.

Here BD is the Hypotenuse.

By Pythagoras Theorem ,

$BD^{2}$ = $AB^{2}$ +$AD^{2}$

$17^{2}$ = $15^{2}$ + $AD^{2}$

289 = 225 +$AD^{2}$

$AD^{2}$ = 289 - 225

$AD^{2}$ = 64

AD = √64

AD = 8m
