WE ALL ARE ALIKE ACCORDING TO THE POET IN THE POEM NO MEN ARE FOREIGN . IN THE WAY WE ALL BREATHE IN THE SAME AIR ,WE ALL WALK ON THE SAME EARTH, WE ALL STARVE TOGETHER DURING THE EXTENDED WAR AND EVEN WE ALL TAKE BIRTH AND DIE IN THE SAME WAY SO THERE IS NO DIFFERENCE BETWEEN US .
Answer:
q1 Given: BC = 48 m, CD = 17 m, AD = 40 m and perimeter = 120 m
Perimeter of trapezium ABCD = AB + BC + CD + DA
=> 120 = AB + 48 + 17 + 40
=> 120 = AB + 105
=> AB = 120 - 105
=> AB = 15 m
Now Area of the field = 1/2 * (BC + AD) * AB
= 1/2 * (48 + 40) * 15
= 1/2 * 88 * 15
= 44 * 15
= 660 m2
Hence, area of the field ABCD is 660 m2.
Step-by-step explanation:
q2 Here h1 = 13 m, h2 = 8 m and AC = 24 m
Area of quadrilateral ABCD = Area of Δ ABC + Area of Δ ADC
= 1/2 * b * h1 + 1/2 * b * h2
= 1/2 * b(h1 + h2)
= 1/2 * 24 * (13 + 8)
= 1/2 * 24 * 21
= 252 m2
Hence, required area of the field is 252 m2.
