Question

A grassy area is in the shape of a trapezoid whose bases measures 150m and 100m and the height is 52m. A 3m walkway is constructed inside this area which runs perpendicular from the two bases. Calculate the area of the grassy patches of land after the construction of this walkway. ​

Answer 1

Area is 0.55 m = 55 cam

h = 11 cm

1/2( sum of bases) *h = 55

1/2(sum of bases)*11=55

sum of bases = (55*2)/11= 11 cut by 55 comes 5

so sum = 5*2=10

Answer 2

Answer:

Step-by-step explanation:

Area of Trapezium= 1/2(sum of parallel sides)× hieght

Area of Trapezium = 1/2(150+100)×52

= 1/2×250×52

=6500 m²

Area of rectangle= l×b

L=52

B=3

Area = 52×3

=156m ²

Area of grassy patches = area of Trapezium- area of rectangle

= 6500-156

=6344 m². Answer
