Answer:
49 ft²
Step-by-step explanation:
The sides of a square are all the same. This means if one of the sides is 7 ft then the others will be too.
To work out the area you have to times two of the sides together.
7x7=49
(ab)/2 = (3 * 6)/2 = 18/2 = 9
Answer:
x=28
y=32
Step-by-step explanation:
You will want to find the area of the whole refuge first. A=b x h. A=650x450. A=292,500. The area of each refuge region is A=25x25. A=625. To find out how many birdhouses you would need you would set up the equation 292,500=625 times x. x=number of bird houses. You would divide 625 from 292,500 getting 468 and that equals x. They will install 468 birdhouses.
