Ms. Newton's flower bed is shaped like a triangle as shown. Find the area of the flower bed in square
feet. If one bag of topsoil covers 10 square feet, how many bags are needed to
cover this flower bed?
b=4
h=2

3 bags are needed to cover the flower bed

Step-by-step explanation:

answer: d. $20

step-by-step explanation:

just took the test

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
