Answer:

403 + 40\sqrt{3}~~ ft^2

Step-by-step explanation:

(20+\sqrt{3})(20+\sqrt{3}) = 20^2 + 2\cdot 20 \cdot \sqrt{3} + \sqrt{3}^2 = 400 + 40\sqrt{3} + 3 = 403 + 40\sqrt{3}

Amanda leaned a 15-foot ladder against the top of her house so she could get on the roof, which is 12 feet from the ground.
valentinak56 [21]

If you're trying to find the missing side of the "triangle" (the distance from the house to where the ladder touches the ground), you would use the pythagorean theorem, a²+b²=c². (c is always hypotenuse)

a²+b²=c²

12²+b²=15²

144+b²=225

b²=81

√b²=√81

b=9
