प्रश्न

Arivu has a land ABCD with the measurements given in the figure. If a portion ABED is used for cultivation (where E is the mid-point of DC), find the cultivated area.

योग

उत्तर

From the figure given ABED is a trapezium with height h = 18 m

One of the parallel side a = 24 m

Since E is the midpoint of D.

Other parallel side b = `24/2` = 12 m

Area of the cultivated ADEB = `1/2` × h(a + b) m2

= `1/2` × 18 (24 + 12)

= 9 × 36 m2 

= 324 m2

Area of cultivation = 324 m2
