Answer:
Option A. 264 ft² ; 4 gallons
Step-by-step explanation:
Given question is incomplete; find the complete question in the attachment.
From the picture attached,
Area of the barn to be painted = Area of the (rectangular base + Triangular top) - Area of the window
Area of the rectangular base = 12 × 18
= 216 ft²
Area of the triangular top =
=
= 60 square feet
Area of the window = 3 ft × 4 ft
= 12 ft²
Total area to be painted = 216 + 60 - 12
= 264 ft²
∵ 70 square feet of the barn is covered by the amount of paint = 1 gallon
∴ 1 square feet will be covered by the amount = gallons
∴ 264 square feet will be painted by =
= 3.77 gallons
≈ 4 gallons
Therefore, Option (A). 264 ft²; 4 gallons will be the answer.
Answer:
2 24" X 24" square cakes are needed.
Step-by-step explanation:
This question is solved by proportions.
Area of a square:
The area of a square of side l is given by:
8" X 8" square cake serves 8 people
Thus:
Area of 64 serves 8 people, so for 1 people, an area of 64/8 = 8 is needed.
144 people
The total area needed is:
How many 24" X 24" square cakes?
24*24 = 576
1 cake - 576
x cakes - 1152
Applying cross multiplication:
1152/576 = 2
2 24" X 24" square cakes are needed.
