Answer:

a. 75 m

Explanation:

Given,

Length of hypotenuse = 18m

Length of perpendicular = 10 m

To find:

Area of the right angled triangle

Formula to find area of the right angled triangle =
(perpendicular * base)/(2)

To find: Length of base

Hypotenuse² = Perpendicular² + Base²

Base² = Hypotenuse² - Perpendicular²

Base² = 18² - 10²

Base² = 324 - 100

Base² = 224

Base =
√(224)

Base = 14.97 m

Area of the right angled triangle =
(perpendicular * base)/(2)


(10 * 14.87)/(2)

⇒ 74.85 m² or,

round to the nearest tenth = 75 m²
