We will solve this using a system of equations. The first part tells us that building a is 190 feet shorter than building b. Our first equation, then, is b=190+a. The second part tells us that the addition of the two buildings' heights is 1480. So our second equation is a + b = 1480. The first equation is already solved for b, so let's sub that value into the second equation for b: a+(190+a)=1480. 2a + 190 = 1480 and 2a = 1290. That means that building a is 645 feet tall. Building b is 190 feet taller, so b = 190 + 645, which is 835.
Answer:
106 m^2
Step-by-step explanation:
First multiply the shaded area:
12 * 10 = 120
Then multiply the white space:
7 * 2 = 14
Then subtract the white space from the shaded area to find the area of only the shaded area.
120 - 14 = 106
Final answer: 106 m^2
I hope this helps!
