उत्तर
The figure obtained by joining the mid-points of the adjacent sides of a rectangle of sides 8 cm and 6 cm is a rhombus of area 24 cm2.
Explanation:
Given: Rectangle with sides 8 cm and 6 cm
To find: Area of the figure which is formed by joining the midpoints of the adjacent sides of rectangle.
Calculation: Since we know that area of rhombus = `1/2 (d_1 xx d_2)`
For rhombus EFGH, EG is the one diagonal which is equal to DA
FH is the other diagonal which is equal to AB
Area of rhombus = `1/2 (d_1 xx d_2)`
Area of rhombus = `1/2 ( 8 xx 6)`
Area of rhombus = `1/2 (48)`
Area of rhombus = 24 cm2
