Answer:
28.8 ft
Step-by-step explanation:
We can use proportion in calculating this.
Let X= height of the shadow of 24- ft tree.
The proportion can be set up as
(15- ft tree) /( 18- ft shadow )=(24- ft tree) / X
15/18 = 24/X
Making X subject of the formula
15X = 18 × 24
X= (18×24)/15
X=28.8 ft
Hence, the shadow of the 24- ft tree is 28.8 feet
