Question

a) a rectangle has breadth 5 cm and a diagonal of length 13 cm. what is the length of the rectangles?

b) a a rectangle has dimensions 12 cm and 16 cm. What is the length of its diaagonals?

c) in a right triangle, if two of the sides measure 15 cm and 20 cm and there is a right angle between these two sides, find the length of the third side.

Note: Please apply the concept of Congruent Triangles and also please draw a rough labelled sketch for all the questions for better understanding.

Answer 1

Answer:

a) We can use the Pythagorean Theorem to find the unknown side of the right triangle, which is also the unknown length of the rectangle. Since the length of the side is a measured distance, the negative root is not a reasonable result. So the length of the rectangle is 12 cm.28-Oct-2016

b)So from the problem we get that the two sides of the rctangle are 16 cm 12 cm which are base perpendicular of the right angle triangle. H = 20 cm. So the diagonal of the rectangle = 20 cm. Ans: 20 cm.
