Given:-

Base = 1.2 m

Hypotenuse = 3. 7 m

Height =?

By Pythagoras theorem, we have

Hypotenuse2 = Base2 + Height2

Height2 = Hypotenuse2 – Base2

Height2= 3.72 – 1.22

Height2 = 13.69 – 1.44

Height2 = 12.25

Height = √12.25

Height = 3.5 m

Then,

Area of right triangle = (1/2) × base × height

= (1/2) × 1.2 × 3.5 = 0.5 × 1.2 × 3.5 = 2.1 m2
