Question

the diagonal of a rectangular field is 20 metres more than the shorter side. if the longer side is 10​

Answer 1

Step-by-step explanation:

let shoter side be x

diagonal = x + 20

longer side = 10

now apply pythagoras

(sideA)² + (sideB)² = diagonal²

》 x² + 10² = (x + 20)²

》 x² + 100 = x² + 400 + 40x

》 40x = -300

》 x = - 7.5

as you can observe we are getting our answer in negative and we know that side of rectangle can't be negative hence data given in question is wrong and it can also be understand by using properties of that triangle that sum of two sides is always greater than third side,
