A rectangle with a length of 3 and a height of 8 has two right triangles on each side of it with short leg lengths of 7.

80 squared units.

Step-by-step explanation:

7 × 8 = 56 u squared for the triangles

you don't need to divide by two because there are two triangles.

3 × 8 = 24 u squared for the rectangle

56 + 24 = 80 squared u

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
