The following shows a rectangle with length a cm and width b cm. (a) Given that the area of the rectangle is Acm2 , express P in terms of a and b. (b) Given that the perimeter of the rectangle is P cm, express P in terms of a and b.
最佳解答:
1a 問題你係未問錯左 (a) Given that the area of the rectangle is Acm2 , express P in terms of a and b. 個P應該係A嘛 1a, A= ab 1b, P = 2(a+b)
其他解答:
1a) area of the rectangle = length * width so A = a * b b) perimeter of the rectangle = ( length + width ) * 2 so P = (a + b) * 2 = 2a +2b
