Question

Find the area if the length is x+7 and the width is x+3 Choose the correct one a) x^2+21 b) x^2+10x+21 c) 2x +10 d) 4x + 20

Answer 1

The area of a rectangle is equal to the length multiplied by the width. In this case, the area would be (x+7)(x+3). Distributing, we get x^2 + 10x + 21. Therefore, the correct answer is b) x^2 + 10x + 21.
