Question

PLS HELP!! Find the missing side

!!

Answer 1

5.59 yd

Explanation:

Answer 2

? ≈ 5.6 yd

Explanation:

the area (A) of a triangle is calculated as

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

here b = 7.4 , h = ? and A = 20.7 , then

`(1)/(2)` × 7.4 × ? = 20.7 ( multiply both sides by 2 to clear the fraction )

7.4? = 41.4 ( divide both sides by 7.4 )

? =
`(41.4)/(7.4)` ≈ 5.6 yd ( to the nearest tenth )
