Answer:

96 units

Step-by-step explanation:

You have to split it into parts then add all together. 3 x 7 equals 21 4 x 7 equals 28 and 5 x 7 equals 35. 4 x 3 equals 12. But you have to split that in half for the area of a triangle. So, 21 + 28 + 35 + 6 + 6 = 96

Answer:

$x=2\sqrt{5}$

Step-by-step explanation:

If that is a square, then all sides are the same. Therefore, it's a $\sqrt{10}$ by $\sqrt{10}$ shape. We'll use Pythagorean Theorem to find the diagonal.

$a^2+b^2=c^2\\\sqrt{10}^2+ \sqrt{10}^2=x^2\\10+10=x^2\\20=x^2\\\sqrt{20}=x\\\sqrt{4*5}=x\\ 2\sqrt{5}=x$

Since it's not a fraction, there is no denominator to rationalize. Let me know if you have any other questions!

Answer:

Area = 31.5 units^2

Step-by-step explanation:

7 x 3 = 21

Area of triangle is (height x base) / 2

(3 x 7) / 2 = 10.5

21 + 10.5 = 31.5
