Answer:
The answer to your question is Perimeter = 110 ft; Area = 600 ft²
Step-by-step explanation:
To find the perimeter, find the hypotenuse of each triangle.
a) Hypotenuse of the large triangle
c² = 18² + 24²
c² = 324 + 576
c² = 900
c = 30 ft
b) Hypotenuse of the small triangle
c² = 7² + 24²
= 49 + 574
= 625
= 25 ft
c) Perimeter = (2 x 30) + (2 x 25)
= 60 + 50
= 110 ft
Area
a) Calculate the area of the large triangle
Area = base x height
= 1/2 (18)(24)
= 216 ft²
b) Calculate the area of the small triangle
Area = 1/2 (7)(24)
= 84 ft²
c) Total area = 2(216) + 2(84)
= 432 + 168
= 600 ft²
