Answer:

120 m²

Explanation:

We khow that the area of a triangle is the product of the lenght and the wight

let x be the width

  • the pythagorian theorem :
  • x²+8²= 17²
  • x² = 17²-8²
  • x²= 225
  • x= 15

so the lenght is 15

  • A= 15*8 = 120 m²

Answer:

120 square meters

Explanation:

The missing leg of the right triangle is found from the Pythagorean theorem:

diagonal² = length² + width²

length² = diagonal² -width²

length = √(17² -8²) = √(289 -64) = √225 = 15

So, the rectangle is 8 m by 15 m and has an area that is ...

A = LW = (15 m)(8 m) = 120 m²
