Answer:
None of the choices are correct.
Step-by-step explanation:
Considering this a right triangle, we may use the law of sines or "sohcahtoa" to find the length of x.
cos(45) = x/100
which equates to about x = 74.29174812021
Answer:
Check my explanation
Step-by-step explanation:
(i) the area of the floor is 30m² (6m · 5m)
(ii) the perimeter of the floor is 22m (6m + 5m + 6m + 5m)
(iii) the area of the walls is:
24m² (for the 6m by 4m walls)
20m² (for the 5m by 4m walls)
88m² in total total
B because one input value is connected to two output values
Answer:
256 cm^2
Step-by-step explanation:
2 of triangulars can be together to become a new square.
because these 2 triangulars have a symmetric shape.
So the all area is 10×16 (the square in the center) + (6×16)
All area is 160 + 96
= 256 cm^2
* the formular of the square area is the width × the length
