Answer:
base = 12 yd
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here A = 24 and h = 4, thus
24 = [tex]\frac{1}{2}[/tex] × b × 4
Multiply both sides by 2 to clear the fraction
48 = 4b ( divide both sides by 4 )
base = 12
