Question

Find the perimeter of a rectangle whose length is 150 cm and diagonal is 170 cm by pythagoras thereom​

Answer 1

Answer:

perimeter = 460 cm

Step-by-step explanation:

let the breadth of the rectangle be x

then by applying the Pythagoras theorem,

170² = 150² + x²

170² - 150² = x²

6400 = x²

√6400 = x

x = 80 cm

⇒ the breadth of the rectangle is 80 cm

now, the perimeter = 2( 150 + 80)

                                = 2 * 230

                                = 460 cm
