Saroj and kavita like to keep themselves physically fit. They jog daily in the morning saroj jogs around a rectangular park of
dimensions Cxy +yz)m and (xy-yz)m, Kavita jogs around a square park of side (2x+3y)m.
a) How much distance does Saroj cover in 5
rounds?
b) How much distance does Kavita coverin!
I round?
c) Find the area of each park.
d) Here which quality do Saroj and Kavita posses
solve step by step
Answers
Answer:
a) 20xy m
b)8x+12y m
C) area of rectangular park =(xy) ^2-(yz)^2
area of square park =4x+9y+24xy
d)
Step-by-step explanation:
a) saroj covers a distance of 4xy m in one round
Therefore perimeter of a rectangle = 2(a+b)
=2(xy+yz+xy-yz)
=2(2xy)=4xy
The distance covered by saroj in five rounds = 5(4xy)=20xy
b) kavitha covers a distance of 8x+12y in one round
Therefore perimeter of a square =4(side)
=4(2x+3y)
=8x +12y
c)area of rectangular park =(xy+yz) (xy-yz)
=(xy) ^2-(yz)^2
Area of square park = (2x+3y)^2
=(2x) ^2 +(3y)^2 + 2(2x)(3y)
=4x+9y+24xy
