Area of Rectangles – Explanation & Examples

WebArea of the rectangle = length × breadth. = 10 × 3 cm 2. = 30 cm 2. Example 3. If the perimeter of a rectangle is 60 cm and its length is 5 times the width, find the area of the rectangle. Solution. Let the width be x. Length is 5 times its width, length = 5x. But the perimeter of a rectangle =2 (l + w) = 60 cm. WebFor example, given that the side corresponding to the 60° angle is 5, let a be the length of the side corresponding to the 30° angle, b be the length of the 60° side, and c be the length of the 90° side.: Angles: 30°: 60°: 90° Ratio of sides: 1:√ 3:2. Side lengths: a:5:c. Then using the known ratios of the sides of this special type of ... WebFind the value of x in each of the triangles below. Round answers to the nearest ten-thousandth. 1. Solution: Using the 39o angle as our reference angle, x is the length of the opposite leg and 15 is the length of the adjacent leg. Therefore, we will use the tangent ratio: Opposite tan( )θ= Adjacent tan(39 ) 15 x D= x =⋅15 tan(39 )D x ≈12. ... idis technical electives
