Question

Please help! would really appreciate it.

Answer 1

Explanation:

Use Pythagorean theorem,

Base² + altitude² = hypotenuse²

15² + altitude² = 17²

225 + altitude² = 289

altitude² = 289 - 225

altitude² = 64

altitude² = 8²

altitude = √8²

altitude = 8

P = 8 + 15 + 17 = 40 units

`A= (1)/(2)*base * height\\\\ = (1)/(2)* 15 * 8\\\\= 15 * 4\\\\= 60 sq. units`
