Let's find the area of the equilateral triangle first:
There are two triangles - one on each end. So we multiply our previous expression by 2.
Each rectangle is 75 millimeters long and 9 millimeters wide: 75*9 mm^2.
We have 3 rectangles each the same size so we multiply 75*9 by 3.
75*9*3 = 2025
2025 + 70.2 = 2095.2
Farenhite conversion of -11℃:
1.8(-11)+32
-19.8+32
12.2℉
difference between 12.2℉ and -80℉:
12.2+80
92.2℉ difference
area of Josephs garden = 9*12 = 108 square feet
area for Alana's garden = 7 *25 = 175 square feet
175/108 = 1.62
Alan's garden is 1.62 times larger
