How do you do this?

10 m²

Step-by-step explanation:

1. First, find the area of the bigger (shaded) rectangle

4 x 3 = 12m²

2. Then, find the area of the door (white rectangle)

2 x 1 = 2m²

3. Because you are only finding the area of the shaded section, you need to subtract the area of the door from the shaded section

12m² - 2m² = 10m²

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
