Question

MNOPQR is a hexagon of side 6cm each. Find its area by dividing it in two trapeziums.
class 8th

Answer 1

Answer:

Since it is a regular hexagon. So, NQ divides the hexagon into two congruent trapeziums. You can verify it by paper folding.

Now area of trapezium MNQR

=4×

2

11+5

=2×16=32 cm

So the area of hexagon MNOPQR=2×32=64 cm

Method adopted by Rushikas

△MNO and △RPQ are congruent triangles with altitude 3cm (fig). You can verify this by cutting off these two triangles and placing them on one another.

Area of MNO=×8×3=12cm

2

= Area of △RPQ

Area of rectangle MOPR=8 5=40cm

2

Now, area of hexagon MNOPQR=40+12+12=64 cm
