Area of a rectangular lawn = l×b
255=15×x
Hence the breadth is 17 m
Hence perimeter =2(l+b)=2(15+17)=64
Answer:what are we supposed to answer give brainl and I’ll come back
Step-by-step explanation:
The simple and easiest way to find it is that you add all the numbers of that value i.e.: 1485=1+4+8+5 it will give u a number which will tell u if it is divisible by what number i mean that: 1+4+8+5=18 so 18 is divisible by 2, 3, 6, and 9
Total distance 5 km; at 5km / 0.65 h =
Second part distance: x; at 6 km/h, during t2
First part distance: 5 - x; at 8.75 km/h, during t1
V = d/t ⇒ t = d/V
t2 = x/6
t1=[5-x]/8.75
t2 + t1 = 0.65
x/6 + [5-x]/8.75 = 0.65
x/6 + 5/8.75 - x/8.75 = 13/20
x/6 - x/8.75 = 13/20 - 5/8.75
x/6 - 4x/35 =13/20 - 20/35
35x - 24x = (35*6)(35*13 - 20*20)/(20*35)
11 x = 16.5
x = 16.5/11 = 1.5 km
