Find the total area
Mila [183]

Answer:

800

Step-by-step explanation:

Find the area of everything first.

30 times 38 = 1140. ( This would be if everything was shaded)

Next, find the area of the mini square.

To do that, calculate the length first.

30-7-6= Length= 17

20 times 17 = 340

1140-340= 800

The flagpole at school casts a shadow that is 18 feet long. A student nearby is 5.5 feet tall and casts a shadow that is 3 feet
azamat

Answer:

33 feet.

Step-by-step explanation:

If the ratio of the student to their shadow and flagpole to its shadow are equal, then you can use the proportion

5.5/3 = x/18 and cross multiply to find x.

5.5 × 18 = 99

3 × x = 3x

3x/3 = x, 99/3 = 33.

x = 33.
