5. Find the area of the composite figure *

187.5 ft²

Step-by-step explanation:

15 x 15 = 225

1/2(5 x 15) = 37.5

225 - 37.5 = 187.5

the area is 187.5

Step-by-step explanation:

First we must split this figure into two, now we have a triangle on top of a rectangle (we know this is a rectangle because the length is longer than the width)

to find the area of a rectangle we must use the equation l*w=A so

15*10=150

Now that we have the area of the rectangle we must find the area of the triangle

We can see one side is longer, this shows us that the triangle is 5 units tall and 15 units long

the formula to find the area of a right triangle is ab/2=A

5*15/2=A

75/2=A

37.5=A

now we have both areas we add them together

37.5+150=187.5

187.5 is your answer

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared
