Find the area of the triangle with height h = 100 km and base b = 200 km. 10,000 km2 1,000 km2 2,000 km2 20,000 km2

150km

Step-by-step explanation:

100x200 is 300. A triangle is half of a square so that answer 300 is for a square you need to divide that in half so the answer is 150.

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%
