Question

the area of a rectangular field is 48 m square and one of its side is 6 metre how long will a lady take to cross the field diagonally at the rate of20 m per minute

Answer 1

area of rectangular field =l*b
48=6b
b=8
so l=8,b=6,h=?
h²=P²+B²
=36+64=100
h²=100
h=10

Answer 2

Answer:

Step-by-step explanation:l×b=48

Let l be 6 the

6×b=48

b=8

By Pythagoras therorem H^2=P^2+B^2

"=(6)^2+(8)^2

"=36+64

H^2=100

H=10m

At the rate of 20=200
