Answer:
745.44 mm² (nearest hundredth)
Step-by-step explanation:
Section the shape into a semicircle, a rectangle and a triangle by drawing a line vertically through the point, and a vertical line upwards from the corner of the 12.5 mm and 32.5 mm corner.
area of semicircle = (1/2) r² = 78.125
mm²
area of the rectangle = 12.5 x 25 = 312.5 mm²
area of triangle = 1/2 x (55 - 25) x 12.5 = 187.5 mm²
total area = 312.5 + 78.125 + 187.5 = 745.44 mm² (nearest hundredth)

When converting decimals to fractions, remember that the numbers after decimal point will be the numerator while the denominator is determined by how many numbers appear.
for one number after decimal point (tenths) you would place the value over 10 [ex. 0.3 = 3/10]
two numbers after decimal point (hundredths) you place the value over 100 [.23 = 23/100]
now you add 7 to this value.
to do so, convert 7/1 to the LCD, which is 100.
7/1 * 100/100 = 700/100
now add .23 to 7
700/100 + 23/100 = 723/100
for one number after decimal point (tenths) you would place the value over 10 [ex. 0.3 = 3/10]
two numbers after decimal point (hundredths) you place the value over 100 [.23 = 23/100]
now you add 7 to this value.
to do so, convert 7/1 to the LCD, which is 100.
7/1 * 100/100 = 700/100
now add .23 to 7
700/100 + 23/100 = 723/100
