Answer:
<em>Well, Your best answer will be is </em><em>24 mm. </em><em>Because, The Pythagorean theorem states that the sum of the squares of the two legs is equal to the hypotenuse squared. </em>
<em>7² ₊ ײ = </em>25². <em>Let's use the × to represent the unknown leg.</em>
<em>49 ₊ ײ = </em><em>625 </em>
ײ = <em>576 </em>
<em>So, Your best choice will be is 24 mm. </em>
<em>Good Luck!</em>

Step-by-step explanation:
ΔADB is a right angled triangle. So, use Pythagorean theorem.
Altitude² = hypotenuse² - base²
= (2√5)² - (3√2)²
= 2²* (√5)² - 3²*(√2)² = 4*5 - 9*2 = 20 - 18 = 2
Altitude = √2
Base of ΔABC = 3√2 + √2 = 4√2 cm
Area =
