The area formula for rectangles is lxw. To solve, I would divide the figure up into 3 rectangles- top,middle and bottom, then find the areas and add them together.
Top: 4x13=52 cm^2
Middle: 5x8=40 cm^2
Bottom: 21x10=210 cm^2
(5 is the width of the middle piece. You get it from subtracting. 21-8-8=5. 13 is the width of the top piece. 5+8=13)
52+40+210
=302 cm^2
So your answer is 302 square centimetres.

I’m assuming “triple 4” is just 3 times 4.
Using the information from the problem, we can form an equation that reads,
3*4 + 7*7
Solve:
12 + 49 = 61
The answer is 61
Answer:
Yes.
Step-by-step explanation:
A linear equation is of the form y = mx + b.
2x = 4y
y = 2x/4
y = 0.5x
so it is linear.
