Question

A rectangular playground 75 m × 45 m has a jogging track of width 3.7 m along its inside edges
Find the area of the going track​

Answer 1

Answer: The area of the jogging track​ is 833.24 sq. m

Step-by-step explanation:

Area of the rectangular playground is = (75 x 45) sq. m = 3375 sq. m

Length of the rectangular playground without the jogging track = (75 - 3.7 - 3.7) m = 67.6 m

Width of the rectangular playground without the jogging track = (45 - 3.7 - 3.7) m = 37.6 m

Area of the rectangular playground without the jogging track = (37.6 x 67.6) sq. m = 2541.76 sq. m

Now, the ares of the jogging track = (3375 - 2541.76) sq. m = 833.24 sq. m

Answer 2

length= 75 m

breadth= 45m

area of playground =75×45

=3375 sq m

length of inner ground =

75- (3.7-3.7)

=67.6

breadth=45-(3.7+3.7

= 37.6

area of inner=67.6×37.6

= 2541.76 sq m

Area of jogging path = area of rectangular park -area of inner ground

= 3375 - 254l.76

=833.24 sq m

I hope its help you
