Question

A rectangular garden 6 meters wide has a diagonal measuring 10 meters. Find the area of the rectangle.

Answer 1

70.2 m²

Explanation:

Area of rectangle = length × width

Pythagorean theorem.

a² + b² = c²

c² - a² = b²

a - side

b - side

c - diagonal

10² - 6² = b²

136 = b²

√136 = b

11.7 = b

11.7 × 6 = 70.2 m²
