Answer 3

Do you know the formulas for calculating the area of a rectangle and triangle?

Answer 4

@keke_luvs_u You there?

Answer 5

@ShadowLegendX no i dont

Answer 6

\[Rectangle: A = l \times w \]

\[Triangle: A = b \times h \div 2 \]

A = Area
l = length
w = width
b = base
h = height

Answer 7

So first lets start with the rectangle

What are its lengths and widths?

Answer 8

ok

Answer 9

is this right??

10 x 19=190 17 x 22 x 17=6,358 190 x 6,358=1,208,020

Answer 10

17 x 22 x 17=6,358 i think this part is right because it was length times height

Answer 11

Let me check

Answer 12

ok

Answer 13

L = 22
W = 17

\[22 \times 17 = 374\]

Rectangle Area = 374

Answer 14

You found the right numbers but you multiplied wrong

Answer 15

Now for the triangle

Answer 16

Now it is tricky to find the measurements of the triangle. But all you have to do is use the rectangles sides to find the base and height of the triangle.

Answer 17

oh

Answer 18

It states that the triangles base is 19 so

B = 19

Answer 19

which base right??

Answer 20

B = base

Answer 21

ok now i got it

Answer 22

Now we can see that the length of the rectangle is 22cm. The triangle is against the side of the rectangle so we can use this to determine the height of the triangle.

Answer 23

ok

Answer 24

so right now are we trying to figuire out the second figuire?

Answer 25

\[22 - 10 = 12\]

The height of the triangle is 12

Answer 26

\[19 \times 12 = 228 \]

Now we must divide 228.

\[228 \div 2 = 114\]

Answer 27

ok

Answer 28

Area of Rectangle: 374

Area of Triangle: 114

Answer 29

i think i no the last part !! now i multiply the two numbers right?

Answer 30

Now since we are to calculate the area of the whole figure we must ---> ADD <--- the two areas of the two figures together.

Answer 31

374 + 114=488

??

Answer 32

\[374 + 114 = 448\]

Answer 33

Correct :)

Answer 34

Do you have any questions?

Answer 35

nope thanks so much
