Question

A right triangle has sides A, B, and C. Side A is the hypotenuse and side B is also a side of a rectangle. Sides A, C, and the side of the rectangle adjacent to side B have lengths of `15`, `2`, and `9`, respectively. What is the rectangle's area?

Answer 1

The area of the rectangle is `133.79(2dp)` sq.unit

Explanation:

`A=15; C=2 :. B= sqrt(15^2-2^2)=sqrt 221 :.B` is a side of rectangle and `D=9` is other side of recangle. The area of the rectangle: `A_r=9*sqrt221 =133.79(2dp)`sq.unit[Ans]
