Question

Find the area please hurry

Answer 1

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) $\pi$r² = 78.125$\pi$ 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$\pi$ + 187.5 = 745.44 mm² (nearest hundredth)
