Step-by-step explanation:
Answer:
B is the answer <em> </em>
<em>because</em><em> </em><em>if</em><em> </em><em>you</em><em> </em><em>observe</em><em> </em><em>very</em><em> </em><em>well</em><em> </em><em>the </em><em>angles</em><em> </em><em>look</em><em> </em><em>simila</em><em>r</em><em> </em><em>in</em><em> </em><em>a</em><em> </em><em>way </em><em>when</em><em> </em><em>you</em><em> </em><em>turn</em><em> </em><em>it</em><em> </em><em>the</em><em> </em><em>other</em><em> </em><em>way</em><em> </em><em>round </em><em>.</em><em>.</em><em>.</em><em> </em>
The area of the little square is x² .
The area of the long skinny rectangle is (length) (width) = (4x) (x) = 4x² .
Add both areas together and you have 5x² ... and we're told that it's 45 cm² .
5x² = 45 cm²
Divide each side by 5 :
x² = 9 cm²
Take the square root of each side:
x = √9
Mathematically, 'x' can be either +3 or -3 . But when you're working with
real shapes on paper, there's no such thing as a length of -3.
So 'x' is just <u>3cm</u><u>.</u>
