Answer:
Am = 1500 cm²
Step-by-step explanation:
If you mean leg around the right angle a = 3 cm and b = 5 cm then :
Formula for calculating area of the right triangle is:
A = a · b / 2 since we have 200 triangles, area of the mosaic is:
Am = 200 · A = 200 · a b / 2 = 200 · 3 · 5 / 2 = 1500 cm²
Am = 1500 cm²
God with you!!!
Answer:
57/99
Step-by-step explanation:
let's set up an equation:
x = 0.5757...
set up a second equation so the numbers after the decimal places are equal
100x = 57.5757...
subtract
100x = 57.5757...
- x = 0.5757
99x = 57
divide by 99
x = 57/99
1/3 of 3/2 of 4/5 would be 0.4
