I would say that every month she puts 90$ and at first she had 197$
the perimeter equation in 2 times the length plus 2 times the height (2 x 8 + 2 x 6) which equals 12 + 16= 28, the area is length times width so 8 times 6 which equals 48
48 ft is the area; 28 ft is the perimeter
We can find the area of each shape separately
The area of the triangle can be found by A = 1/2bh
So the area will be 1/2 times (6+14+6= 26) 26 times 21
The area of the triangle will be 273 ft^2
The area of the square will be A=lxh
So the area will be 14 times 14
So the area of the square will be 196 ft ^2
We then add the area of both shapes together to get the total area
273 + 196 = 469 ft^2
