Detailed Solution
Download Solution PDFGiven:
The breadth of the rectangle = 8 cm
The diagonal of the rectangle = 17 cm
Formula Used:
(Diagonal)2 = (Length)2 + (breadth)2
Area of the rectangle = Length × breadth
Calculation:
(Diagonal)2 = (Length)2 + (breadth)2
⇒ (17)2 = (Length)2 + (8)2
⇒ Length = √(289 - 64)
⇒ Length = √225
⇒ Length = 15 cm
Area of the rectangle = Length × Breath
⇒ 15 × 8
⇒ 120 cm2
∴ The area of the rectangle is 120 cm2.Last updated on Jul 17, 2025
