Answer:
Correct option is A)
Length of garden =48 m
Breadth of garden =32 m
Perimeter =2(48+32)m=160 m
∴ Length of fencing used to enclose the garden =160 m
Cost of fencing 1 m=Rs.98
∴ Cost of fencing 160 m=Rs.(98×160)=Rs.15680
So, total cost =Rs.15680.

Verified answer
Answer:
1. a) x+3 = 15
x=15-3
x= 12
b) a-7 =18
a= 18-7
a= 11
2. 36 and a will in a pair and 90 and 90 will in a pair
36a = 90*90
36a = 8100
a = 8100/36
a= divide it
3. perimeter of triangle = 2(l+b)
p = 2(40+ 25)
p = 2*65
p= do it
cost of fencing = your answer/34 = ₹ your answer
