Answer:
100 ft^2
Step-by-step explanation:
The large upper rectangle has dimensions 12 ft by 23 ft, and thus has area 276 ft^2. The small lower rectangle is 15 ft by (12 - 7) ft, or 15 t by 5 ft, and thus has area 75 ft^2. The total area is
75 ft^2 + 25 ft^2, or 100 ft^2.
200 flying insects she catch for her project .
<u>Step-by-step explanation:</u>
We have , Heather had to collect insects for her biology project. She was able to collect 225 total insects. She collected 8 times as many insects that could fly as insects that couldn't fly. That means insects ratio of non-fly to fly is 1:8 .
There are a total of 225 insects , and for every one non fly insect there are 8 fly insects , Let x be the number of insects that can't fly so:

⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
So , Number of fly insects = 8x = 8(25) = 200 . ∴ 200 flying insects she catch for her project .
