Question

The adjacent sides of a rectangle are 8cm and 4cm . Find the length of its diagonal​

Answer 1

Answer:

diagonal=8.94cm

Step-by-step explanation:

d=√ (w2+l2)

d=√ (8^2+4^2)

d=√ (64+16)

d=√ (80)

d=8.94

Answer 2

Answer:

• 8.94 cm

Step-by-step explanation:

Given

• Adjacent sides of rectangle

1. 8 cm
2. 4 cm

To find

• Length of the diagonal

Solution

Diagonal length :

• Diagonal² = Length² + Breadth²
• D² = 8² + 4²
• D² = 64 + 16
• D² = 80
• D = √80
• D = 8.94

Hence, the length of the diagonal is 8.94 cm.
