Answer:
Step-by-step explanation:
Let breadth = x cm
length = ( x + 2 )cm
because length is 2cm more than a breadth
perimeter = 28cm
2 ( l + b ) = 28
2 ( x + x + 2 ) = 28
2 ( 2x + 2 ) = 28
2x + 2 = 28/2
2x + 2 = 14
2x = 14 - 2
2x = 12
x = 12/2 = 6cm
length = x + 2 = 6 +2 = 8cm
breadth = x = 6cm
b)Price of per Packets = 125/25
→ Price of per Packets = 5
Now, No. of Packets = Total Rate * Rate of per Packet.
→ No. of Packets = 170 * 5
→ No. of Packets = 850
Hence, Raju can purchase 850 packets of the same chocolate for Rs. 170.
c) IF WE WILL ADD 3.875 TO THE 6.125. THEN THE SUM WILL BE 10. 6.125-10= 3.875.
d)
Answer:
Correct option is
C
143
Let breadth of the rectangle be 'b' cm.
So length of the rectangle will be 'b+2' cm.
Now
Perimeter =48
2(l+b)=48
2(b+2+b)=48
2b+2=24
2b=22
b=11 cm
l=b+2=13 cm
Then,
Area of the rectangle =lb
=13×11
=143 cm
