![]() ![]() The question asks for the length and width of the rectangle, these has been found and checked. The perimeter is 46 cm which matches the information given in the question. Is my solution correct?Ĭheck the answer by calculating the perimeter of the rectangle. So the length of the rectangle is 13 cm and the width is 10 cm. The length of the rectangle is: \(2x 5\) The perimeter of the rectangle is 46 cm, therefore:įind the length and width of the rectangle by substituting the value of \(x\) into the expressions for the length and width. The width of a rectangle is seven meters less than the length. The perimeter of a shape is found by adding up all the sides. Write on the lengths ( expressions ) of the other sides on your diagram. What information don’t I need?Įverything in this question is relevant to working out the answer. The answer might be a whole number or a fraction or decimal. The question asks you to find the length and width of the rectangle, and to do this you have to find the value of \(x\). The key word in the question is perimeter. The highlighted words are the most important ones. Solved examples to find the area of a rectangle when length and breadth are given. ![]() ![]() Highlight or underline the important pieces of information in the question. So when we multiply its length and breadth we get the area of the rectangle. įind the length and width of the rectangle. The width of the rectangle is \(3x - 2\). The length of the rectangle is \(2x 5\). The solution involves factoring a trinomial, which is done using the Diamond Method of factoring.
