Answer:
118.3 m²
Step-by-step explanation:
The area (A) of a triangle is
A = bh ( b is the base and h the perpendicular height )
Note the legs 13 and 18.2 are at right angles to each other, hence
A = 0.5 × 13 × 18.2 = 118.3
It makes it easier to multiply. For example 2*52. It's easier to do 2*50 and then 2*2 and add it together. Product is 104
