Marysya12 [62]

Answer:

9.7303888 miles

Step-by-step explanation:

Given the following :

Set target = 12 miles per week.

Miles ran on Monday = 4 3/4 miles

Miles ran on Wednesday = 3 1/3 miles

Miles ran on Friday = 1 11/17 miles

Number of miles covered for the week:

(miles covered on Monday + miles covered on Wednesday + miles covered on Friday)

= (4 3/4 + 3 1/3 + 1 11/17) miles

= (19/4 + 10/3 + 28/17) miles

= (4.75 + 3.33333 + 1.6470588) miles

= 9.7303888 miles

Find the area of these shapes AND explain your method Can some one help me :((

-Dominant- [34]

Answer:

Triangle - 21 units

Trapezoid - 65 units

Step-by-step explanation:

Because this triangle and trapezoid are reflections of each other when split in half, remove the highlighted parts to make them a rectangle. When made into a rectangle, you can use the formula length * width to find the area of either shape (trapezoid or triangle).
Note you won't be able to do this when solving for the area of ALL trapezoids and triangles.
