First, find the area of the surface of the shed. Two walls will have an area of 14 x 8 and two walls will have an area of 18 x 10. We get the equation 2(14x8) + 2(10x8) = 224 + 160 = 384 square feet
Next, divide the square footage of the shed's surface by 250 to find how many gallons of paint are needed. 384/250 = 1.54 gallons of paint (rounded to the nearest hundredth)
For the triangle questions, remember that the area of a triangle is
$13.10. This is because you multiply $5.50 x 2 due to the amount of cars which leaves you off with $11 total. Then you take away $11 from the total price of $142 which leaves you off with $131.00 from there you divide the amount of people going which is 10. So you’ll get 131/10 = $13.10
