Question 436524
Find the exact perimeter of the rectangle. Then approximate your answer.
√18cm
√50cm
---
Note: I'm guessing those are the length and the width.
---
Perimeter = 2(length + width)
P = 2(sqrt(18)+sqrt(50)]
P = 2[3sqrt(2) + 5sqrt(2)]
P = 2sqrt(2)(8)
P = 16sqrt(2)
=======================
The exact perimeter of the rectangle is 16sqrt(2) cm
Type an exact answer using radicals as needed.
====================
Approximate answer is 16*1.414 = 22.6 cm
