Answer 1

GivEn:

• Length of rectangle = 8cm
• Breadth of rectangle = 6cm

To find:

• Diagonal of rectangle ?

Solution:

• Let's consider ABCD is a rectangle.

Where,

• Base = Length = 8 cm
• Perpendicular = Breadth = 6 cm
• Hypotenus = Diagonal

• Let Breadth of rectangle be b m.

⠀⠀━━━━━━━━━━━━━━━━━━━⠀

« Now, By using Pythagoras Theorem,

→ (Perpendicular)² + (Base)² = (Hypotenuse)²

→ h² = (6)² + (8)²

→ h² = 36 + 64

→ h² = 100

→ √h² = √100

→ h = 10 cm

∴ Hence, Diagonal of the rectangle is 10 cm.

⠀⠀⠀ ★ Additional information:

• sinθ = opp/hyp
• cosθ = adj/hyp
• tanθ = opp/adj
• cotθ = adj/opp
• cscθ = hyp/opp
• secθ = hyp/adj
• sin x = cos ( 90° - x )
• cos x = sin ( 90° - x )
• tan x = cot ( 90° - x )
• cot x = tan ( 90° - x )
• sec x = cosec ( 90° - x )
• cosec x = sec ( 90° - x )
