Suppose the shorter side is 2x cm. Then the longer side is 3x cm By Pythagoras, (2x)2 + (3x)2 = 262 ie 4x2 + 9x2 = 262 so that 13x2 = 262 x2 =52 so that x = 2*sqrt(13) Then perimeter = 10x = 20*sqrt(13)
524
80°F = 262/3°C To convert Celsius to Fahrenheit, the formula is F = 9/5C + 32. If the Fahrenheit reading is 3 times the Celsius reading then F = 3C, so 3C = 9/5C + 32 : 6/5C = 32 : C = 262/3. Then F = 3C = 3 x 262/3 = 80
To find half of a number, you simply divide the number by 2. In this case, to find half of 524, you would divide 524 by 2. The result of this division would be 262. Therefore, half of 524 is 262.
Every triangle is unique, so this question cannot have a serious answer.
