Question

find the value of y for which the perimeter of the following figure os 100 cm length 2y +9 breadth 3y + 24​

Answer 1

Answer:

18/5

Step-by-step explanation:

perimeter =2(l+b)

100=2{(2y+8)+(3y+24)}

100=2{2y+8+3y+24}

100=4y+16+6y+48

100=10y+64

10y=100-64

10y=36

y=36/10

y=18/5

Answer 2

Answer:

17/5

Step-by-step explanation:

perimeter =2(l+b)

100=2{(2y+9)+(3y+24)}

100=2{2y+9+3y+24}

100=4y+18+6y+48

100=10y+66

10y=100-66

10y=34

y=34/10

y=17/5
