Answer 10 :-

Given :-

Area of square = 5625m²

To Find:-

Side = ?

As we know that :-

Formula of area of square = l²

$\bold \color{brown}=> l² = 5625$

$\bold \color{brown}=> l \: = \sqrt{5625}$

$\bold \color{brown}=>l \: = 75m$

∴ Side of a square is 75m.

Answer 11:-

(1) 0.1

$\bold \color{brown}=> 0.1 ×0.1 ×0.1$

$\bold \color{brown}</p><p> => 0.001$

(2) -2/3

$\bold \color{brown} = > { (\frac{ - 2}{3} )}^{3}$

$\bold \color{brown} = > ( \frac{ - 8}{27} )$

Answer 12:-

(4a² - a + 5)-(a²-5a+6)

$\bold \color{brown} =>4a²-a+5-a²+5a-6$

$\bold \color{brown}=>4a²-a²-a+5a+5-6$

$\bold \color{brown}=>3a²+4a-1$
