Chapter 7 - Geom 3) The diagram below shows quadrilateral
PQRS. If PQRS is a rhombus:
2x-3y
40 cm
30 cm
2y
S
R
a) Determine the values of x and y stating
all reasons where necessary.
b) Determine the length of PS stating all
reasons where necessary.​

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to
