Question

Find length of rectangle having breadth 8units and diagonal 17 units
$13 units$
​

Answer 1

Answer:

Answer:

h² = b²+p²

(17)² = (b)²+(8)²

289= b²+ 64

289-64 =b²

225 = b²

(15)² = b²

b = 15 units

length = 15 units

Answer 2

Answer:

15

Step-by-step explanation:

In the figure

AC is the diagonal

AB is the base

BC is the altitude

By applying pythagorean theorem

Hyp² = B² + Alt²

AC² = AB² + BC²

AB² = AC² - BC²

AB² = (17)² - (8)²

AB² = 289 - 64

AB² = 225

AB = √(225) = 15 units

AB is the Length of the rectangle ABCD = 15 units

BC is the breadth of the rectangle ABCD = 8 units
