There is 2 figure here, a triangle and a parallelogram.
Area of parallelogram=base * height
A=9 * 5
A=45m²
Area of triangle= $\frac{1}{2}$ (base * height)
A= $\frac{1}{2}$ (9*8)
A= $\frac{1}{2}$ 72
A=36m²
36+45=81m²
The area of this figure is 81m²

Answer: The starting time is 2:27 and finishing time is 7:09.

Step-by-step explanation: It is given that Ben started from 4th street and he finished at 98th street.

Also, at 3:00, he was on 15th street and at 4:30, he was on 45th street.

That is, time taken to cover (45-15), i.e., 30 streets is 90 minutes, so the time taken to cover 1 street is 3 minutes.

Therefore, Ben covers distance from one street to second in 3 minutes. Since he started from 4th street, and there are 11 streets to cover between 4 and 15, so Ben's starting time was (3:00 - 3×11 min) = 2:27.

And his finishing time was (4:30 + 3×53 min) = 7:09.

Again, the equation that tells us on what street 'N' he was after time 'T' of his starting can be written as

$N=4+\dfrac{T}{3.}$
