Question

please answer the 45th question

Answer 1

Length of the rectangle = 40m
Breadth of the rectangle = 30m

Area of the rectangle = L*B

= 40 * 30 = 120sqm

Length of one path = 40m
width = 1m

Area = 40m *1m

= 40sqm

length of two paths = 40sqm *2

= 80sqm


Length of one path = 30m
width = 1m

Area = 30m * 1m

= 30sqm

Length of two paths = 30sqm *2

= 60sqm
Area of shaded paths = 120sqm - (80sqm + 30sqm)

= 120sqm -110sqm
=10sqm.
