Plot the point (4, 0) (the x-intercept) and then the point (0, -3) (the y-intercept). Draw a straight line through these two points.
Answer:
460 m
Step-by-step explanation:
Use right triangle PSR with right angle S to find the length of PS.
The Pythagorean theorem can be used for this.
a^2 + b^2 = c^2
(PS)^2 + (SR)^2 = (PR)^2
(PS)^2 + (150 m)^2 = (170 m)^2
(PS)^2 = 22500 m^2 = 28900 m^2
(PS)^2 = 6400 m^2
PS = 80 m
PS = 80 m; SR = 150 m
perimeter = 2(length + width)
perimeter = 2(150 m + 80 m)
perimeter = 2(230 m)
perimeter = 460 m
