First you need to find area of square which is side x side which is 8x8 which is 64. Then you find the side of the triangle which is 14-8 which is 6 then you need to find the height of the dotted line I’m pretty sure there’s a formula but it looks like it’s 8 because it looks like a square so then the formula of a triangle is base times height divided by two so the base is 6 and height is 8 so 6x8 which is 48 and divided by two is 24 then you add the area of the triangle and the area of the square which is 64 so 64+24 which is 88 so I’m pretty sure the area is 88 then just put whatever units after :)

A jet travels from chicago to kansas city at a speed of 440 knots. If it takes a plane 3 hr longer to fly from kansas city to ch
steposvetlana [31]

d = distance between the two cities

v₁ = average speed while going from chicago to kansas city = 440 knots

t₁ = time taken to travel distance going from chicago to kansas city

time taken to travel distance going from chicago to kansas city is given as

t₁ = d/v₁

t₁ = d/440                                        eq-1


v₂ = average speed while going from kansas city to chicago = 110 knots

t₂ = time taken to travel distance going from kansas city to chicago

time taken to travel distance going from kansas city to chicago is given as

t₂ = d/v₂

t₂ = d/110                                                     eq-2


Given that :

t₂ = t₁ + 3

using eq-1  and eq-2

(d/110) = (d/440) + 3

d = 440
