let x be the two sides 90deg to the house
house side = 180-2x
Draw a rectangle with length of 2 sides at right angle to house=x
Length of side parallel to house=180-2x
Garden area=x(180-2x)
=180x-2x^2
=-2x^2+180
x
complete the square:
=-2(x^2-90x)
=-2(x^2-90x+2025)+4050
=-2(x-45)^2+4050
so area is max at x-45=0
x=45
House side=180-2*45=90
Garden with the greatest area: 45 by 90 ft
Greatest area=45*90=4050 sq ft
Green is 50 and the blue is 30 degrees

<u>Answer:
</u>
An adolescent snail’s mass is 60% of an adult. The adolescent snail’s mass is 39 grams .The adult mass is equal to 65 grams.
<u>Solution:
</u>
Given that adolescent snail’s mass is 60% of an adult.
Let assume mass of an adult = x grams
So adolescent snail’s mass = 60% of x grams
adolescent snail’s mass = --- eqn 1
From question, it’s given that adolescent snail’s mass is 39 grams.
So we can say eqn1 is equal to 39
3x=195
x = 65 grams
Hence the adult mass is equal to 65 grams.
