Whats the area of the lawn in this shape

Licemer1 [7]

Answer:

208 ft

Step-by-step explanation:

in order to do this we need to find the area of the retangle:

(l x w) 14x20= 280ft

then the area of the rectangle:

a^2 + b^2 = c^2 ( hypotenus lenght )

c= 8.5

now we can plug in to find the area of the triangle, which is 12 (11.99)

then the area of the trapezium= 60

finally we can find the answer

280 - (60+12)= 208 ft :)

What is the slope of the line through (6,0) and (7,1)

monitta

$\huge \bf༆ Answer ༄$

Let's find the slope of line passing through given points ~

$\sf \dfrac{y2 - y}{x2 - x1}$

$\sf \dfrac{1 - 0}{7 - 6}$

$\sf \dfrac{1}{1}$

$\sf1$

Hence, slope of the line will be 1.
