Help plz! Will mark as brainiest JUST HELP PLZ

Answer 1

1) The lengths of the other 2 sides are 51 feet.

Isosceles triangles have at least 2 equal sides. The base is 60 feet, so we can assume that the other 2 sides are equal

162 = 60 + 2x

x = the equal sides of the triangle.

162 - 60 = 102

102 = 2x

Divided by 2

51 = x

51 + 51 = 102. 102 + 60 = 162

2)

Pool 1: 311.38ft.

8*19.4 = 155.2

8 * 5.7 * 2 = 91.2

5.7 * 5.7 = 32.49/2 (because its a triangle) = 16.254*4 = 64.98

155.2 + 91.2 + 64.98 = 311.39

Pool 2: Either 863.94ft or 484 + 121πft

22 * 22 = 484

22/2 = 11, So, the radius of the half circle is 11

Circle area = (pi)r^2

11*11 = 121

pi * 121 = 121pi

Using 3.14 substitute: 3.14 * 121 = 379.94

379.94 + 484 = 863.94

Pool 3: 207ft

Rhombus area = pq/2

18 * 12 = 216

216/2 = 108

11 * 18 = 198/2 = 99

99 + 108 = 207
