Question

Find the missing part . Round the triangle to the nearest tenth.

Answer 1

11.4 mi

Explanation:

The area (A) of a triangle is calculated as

A =
`(1)/(2)` bh ( b is the base and h the height )

Here A = 41.6 and h = 7.3 , b is to be found, thus

`(1)/(2)` × 7.3b = 41.6, that is

3.65b = 41.6 ( divide both sides by 3.65 )

b ≈ 11.4 ( to the nearest tenth )

Answer 2

length = 11.4 mi

Explanation:

Area of triangle = 1/2 * height * length - Now, lets substitute

41.6 = 1/2 * 7.3 * length - Now, lets solve the equation!

length = 11.3972602739726 - round it up to the nearest tenth

length = 11.4 mi
