Question

The area of a rectangle is 99 square units. Its width measures 9 units. Find the length of its diagonal. Round to the nearest tenth of a unit.

Answer 1

Answer:

14.21 units (14.2)

Step-by-step explanation:

Formula for area is W(L) or width multiplied by length.

The formula for finding the length of a rectangle's diagonal is :

d = $\sqrt{w^{2}+l^{2} }$

Now we solve for d.

d = $\sqrt{w^{2} + (\frac{A}{W})^{2}$

= $\sqrt{9^{2} + (\frac{99}{9})^{2}$

≈ 14. 21267

≈ 14.2
