Question

Help me out please!!! 50 points!!!

Answer 1

Pythagoras theorem

diagonal² = length² + width²

$13²$ = $12²$ + width²

$169$ = $144$ + width²

$25$ = width²

width = $5$m

so, Oakdale Avenue is $5$m wide.

Answer 2

Step-by-step explanation:

I assume they intersect at a right angle (90°).

then the intersection is a rectangle with one side being 12 m, and the diagonal being 13 m long.

the diagonal is the Hypotenuse (baseline) of a right-angled triangle with the length and the width of the rectangle as legs.

so, by using Pythagoras we have

diagonal² = length² + width²

13² = 12² + width²

169 = 144 + width²

25 = width²

width = 5 m

so, Oakdale Avenue is 5 m wide.
