They read for 39 minutes as that is the difference in time from when they started to when they finished.
The area of a triangle is calculated by the expression given as:
Area = bh/2
where b is the base and h is the height.
We calculate as follows:
270 = b (15) / 2
b = 36
<span>hypotenuse = sqrt ( 15^2 + 36^2 ) = 39</span>
Answer:
where's the work? or do you need help with sum else?
