Let, the width of the rectangle is x meters

So, the length of the rectangle is = (x+10) Meters

According to the question,

$x (x + 10) = 1, 200 \Rightarrow x^{2} + 10 x - 12, 00 = 0 \Rightarrow x^{2} + 40 x - 30 x - 1, 200 = 0 \Rightarrow x (x + 40) - 30 (x + 40) = 0 \Rightarrow (x + 40) (x - 30) = 0 \Rightarrow x - 30 o r, x = - 40 (B u t t h e v a l u e o f l e n g t h c a n n o t b e a n e g a t i v e)$

So, the width of the rectangle is 30 meters, and

The length of the rectangle = 30+10=40 meters.

So, according to the Pythagorean theories.

The length of the diagonal of the rectangle= $\sqrt{40^{2} + 30^{2}} = 50$ meters.
