Answer 1

Step-by-step explanation:

let length of rectangle be x

width is x-7

as per pythogoras theorem

h²= l²+w²

(13)²= x²+(x-7)²

169= x²+x²+49-14x

120= 2x²-14x

60= x²-7x

equation = x²-7x-60

on solving eq

x²-12x+5x-60= 0

x(x-12)5(x-12)

(x-12)(x+5)

x= 12,5

as length can not be negative

length of rectangle= 12cm

width is 5cm
