Question

if a rectangle has length is 20m and breath is 15 cm then find all length of diagonal

​

Answer 1

Answer :

• Length of Diagonal is 25cm

Given :

• length is 20cm
• Breadth is 15cm

To find :

• length of Diagonal

Solution :

Let Diagonal of rectangle be x

As we know that , Pythagoras theorem,

• (D)² = (l)² + (b)²

where d is Diagonal, l is length and b is breadth

• Diagonal be x
• length is 20cm
• breadth is 15cm

⇢ (D)² = (l)² + (b)²

⇢ x² = (20)² + (15)²

⇢ x² = 400 + 225

⇢ x² = 625

⇢ x = √625

⇢ x = 25

Hence , Length of Diagonal is 25cm

Answer 2

Answer:

Length of Diagonal is 25cm

Given :

length is 20cm

Breadth is 15cm

To find :

length of Diagonal

Solution :

Let Diagonal of rectangle be x

As we know that , Pythagoras theorem,

(D)² = (l)² + (b)²

where d is Diagonal, l is length and b is breadth

Diagonal be x

length is 20cm

breadth is 15cm

⇢ (D)² = (l)² + (b)²

⇢ x² = (20)² + (15)²

⇢ x² = 400 + 225

⇢ x² = 625

⇢ x = √625

⇢ x = 25

Hence , Length of Diagonal is 25cm.
