Question

The area of the
yellow rhombus is
38 cm^2. If the
vertices of the
rhombus
are
midpoints of the
sides
of
the
rectangle, what is
the area (in cm) of
the portion of the
figure that is shaded
red?​

Answer 1

38

Step-by-step explanation:

in this type figure diagonal (d1) of rhombus will be = length of rectangle(l) & diagonal (d2) of rhombus = breath of rectangle(b)

since, area of rhombus = 38 cm^2

d1×d2/2 = 38 => d1× d2 = 76

=> l×b = 76 = area of rectangle

area of portion shaded red

= area of rectangle - area of rhombus

= 76 - 38 = 38 cm^2
