1.	A took 15 sec to cross a rectangular field diagonally walking at a rate 52 per minute and the B took the same time to cross the same field along with side walking at 68 m/min the area of field is?
Answer» ANSWER: 29.6250 meter square Step-by-step explanation: diagonal (l^2 + b^2) = 15* 52/60 = 13m 2(l+b) = 1568/60 =17 m (l+b)^2 = l^2 + b^2 + 2 lb (17/2)^2 =13 + 2 lb lb = 29.6250 meter square

Answer»

ANSWER:

29.6250 meter square

Step-by-step explanation:

diagonal (l^2 + b^2) = 15* 52/60 = 13m

2(l+b) = 15*68/60 =17 m

(l+b)^2 = l^2 + b^2 + 2 l*b

(17/2)^2 =13 + 2 l*b

l*b = 29.6250 meter square
