Question

Patricia has a lawn, ABCD. She has placed a watering hose, BD, as shown below.

Answer 1

Part A: Patricia plans to put a fence along the length AD of her lawn. What is the length of the fence required?
Part B: Using complete sentences, explain how you arrived at the answer for Part A.

Answer 2

please help! i dont remember how to solve this and its really frustrating

Answer 3

first, u have to find out the length of a watering hose, BD
use the pythagorean theorem :
BD^2 = BC^2 + CD^2

Answer 4

Okay so this would be BD^2= 30^2 +16^2? which should equal to 900+256= 1156.. but you still need to square it.. which is 1336336..so this means that would be equal to BD? that doesnt sound right lol i must have done somthing wrong

Answer 5

BD^2 = BC^2 + CD^2
BD^2 = (30)^2 + (16)^2
BD^2 = 900 + 256
BD^2 = 1156

take the squareroot,
BD = sqrt(1156)
BD = 34

Answer 6

okay was close, so now, what must i do with the measure of BD? it says "Patricia plans to put a fence along the length AD of her lawn. What is the length of the fence required? am i supposed to find the meansure of AD too?

Answer 7

yes,
then look at the triangle of ABD, are u familiar with the 30-60-90 right triangle ?

Answer 8

yes i am
