Answer:
The area of rhombus PQRS is 120 m.
Explanation:
Consider the rhombus PQRS.
All the sides of a rhombus are equal.
Hence, PQ = QR = RS = SP = 13 m
The diagonals PR and QS bisect each other.
Let the point at of intersection of the two diagonals be denoted by X.
Consider the triangle QXR.
QR = 13 m
XR = 12 m
The triangle QXR is a right angled triangle.
Using the Pythagorean theorem compute the length of QX as follows:
QR² = XR² + QX²
QX² = QR² - XR²
= 13² - 12²
= 25
QX = √25
= 5 m
The measure of the two diagonals are:
PR = 2 × XR = 2 × 12 = 24 m
QS = 2 × QX = 2 × 5 = 10 m
The area of a rhombus is:
![\text{Area}=(1)/(2)* d_(1)* d_(2)](https://img.qammunity.org/2021/formulas/mathematics/high-school/ih06qenwvv6l7wk2e6r26u3g95us7srjzn.png)
Compute the area of rhombus PQRS as follows:
![\text{Area}=(1)/(2)* PR* QS](https://img.qammunity.org/2021/formulas/mathematics/high-school/uqx01f1vjbqm9dbep0qzx5ieprtbtjf6t7.png)
![=(1)/(2)* 24* 10\\\\=120](https://img.qammunity.org/2021/formulas/mathematics/high-school/ig6um87gndlmlyxvn9c622spzvfejyp33x.png)
Thus, the area of rhombus PQRS is 120 m.
