Answer:

c. 441ft^2

Explanation:

Area is height times length and since it's a square, safe to say that the sides are equal in length. So square root both of the given areas of the 2 square:


√(841) = 29


√(400) = 20

Now u have side b and c of the triangle, it's a right triangle so use the Pythagorean theorem a^2 + b^2 = c^2

a^2 + b^2 = c^2

a^2 + 20^2 = 29^2

a^2 + 400 = 841

subtract 4 from both sides

a^2 = 441

square root both sides


√(a^2) = √(441)

a = 21

Now the side a of the triangle is also a side of the small square therefore

21^2 = 441
