Solution

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
